Surveillance Radars Market - Global Forecast 2026-2032

The Surveillance Radars Market size was estimated at USD 10.70 billion in 2025 and expected to reach USD 11.64 billion in 2026, at a CAGR of 9.59% to reach USD 20.32 billion by 2032.

Surveillance radars are becoming foundational assets for air defense, maritime domain awareness, border protection, critical infrastructure security, and civil aviation continuity. Their value is shifting from stand-alone detection to networked sensing that fuses primary radar, secondary surveillance radar, ADS-B, electro-optical inputs, AIS, space-based data, and command-and-control feeds into a recognized operating picture. This shift is being driven by hypersonic and cruise missile risks, low-altitude drone activity, contested maritime routes, illegal fishing, narcotics trafficking, and the need to protect airports, ports, energy assets, and military bases. The modernization imperative is visible in civil aviation as well: the U.S. aviation authority reported 618 radar systems and a FY2025 proposal to modernize 377 critical radar systems averaging 36 years of age, while also noting that ADS-B cannot fully replace radar because not all users carry required avionics.

The surveillance radar landscape is undergoing a structural transition from hardware-centric acquisition to integrated, software-defined, and data-fusion architectures. Active electronically scanned arrays, over-the-horizon radar, passive sensing, counter-UAS radar, maritime coastal radar, and multi-function air and missile defense sensors are converging around interoperability, low-latency data exchange, and electromagnetic resilience. NATO’s 2025 Integrated Air and Missile Defence policy defines air surveillance as one of four functional areas of IAMD, placing radar-generated situational awareness at the center of allied defense operations. Civil airspace is experiencing a parallel transition, with ADS-B established as a preferred surveillance method in the U.S. National Airspace System while radar remains essential for unequipped aircraft, resilience, and defense-related missions. Drone proliferation is also changing requirements: NATO’s 2024 counter-UAS interoperability exercise involved 450 participants from 19 Allied nations and three Partner nations, demonstrating how radar, RF, electro-optical, and command systems must work together against small, low-flying threats.

Artificial Intelligence is compounding the operational value of surveillance radars by improving clutter suppression, target detection, track correlation, automatic target recognition, anomaly detection, and operator decision support. Peer-reviewed radar research has documented growing use of deep learning for jamming and clutter recognition, waveform and array design, radar imaging, and automatic target recognition, while aerial-threat studies emphasize detection, classification, and tracking challenges for unmanned systems. The cumulative impact is not simply faster processing; it is a new operating model in which radar data becomes part of a continuously learning sensor-to-decision chain. However, AI-enabled surveillance radars require rigorous governance because false positives, adversarial manipulation, data drift, and opaque classification can undermine mission trust. NIST’s AI Risk Management Framework and NATO’s revised AI strategy both emphasize safe, responsible, and trustworthy AI adoption, reinforcing the need for human oversight, validation datasets, cyber-secure models, and explainable outputs in high-consequence radar missions.

In Asia-Pacific, surveillance radar priorities are shaped by dense airspace, contested maritime zones, missile risks, and coast guard modernization. India’s Coast Guard reports a Coastal Surveillance Network with radars, AIS, day-night cameras, and meteorological sensors at 46 locations, with Phase II adding 38 radar stations and eight mobile surveillance systems to move toward near gap-free coastal coverage. Australia continues to prioritize integrated air and missile defense, over-the-horizon sensing, and naval radar renewal, including phased-array radar replacement for eight Anzac-class frigates with final operating capability listed for July 2025.

Latin America is emphasizing border, jungle, airspace, and maritime surveillance: Brazil’s defense ministry highlights SISFRON for the country’s 16,886 kilometers of land borders, while Mexico reported that CENAVI reached 62% national airspace surveillance coverage in 2024. Europe is accelerating radar-linked air and missile defense cooperation after the 2024 CARD report identified integrated air and missile defense as crucial for protecting infrastructure, urban areas, and forces from ballistic missiles, cruise missiles, and unmanned aircraft. The Middle East is centered on integrated air and missile defense and maritime security, reflected in 2024 U.S.-GCC defense working groups on IAMD and maritime security. Africa’s radar opportunity is tied to maritime security, fisheries protection, and regional information sharing, with SADC establishing a regional fisheries monitoring, control, and surveillance coordination center and Gulf of Guinea partners using the Yaoundé Architecture to strengthen maritime domain awareness.

Across ASEAN, surveillance radar relevance is anchored in maritime security, archipelagic domain awareness, humanitarian response, and airspace coordination, with ASEAN-U.S. cooperation documents emphasizing maritime security and defense engagement and Japan-ASEAN discussions focusing on maritime cooperation, connectivity, joint training, and capacity building. Within the GCC, radar-linked priorities are concentrated around integrated air and missile defense, maritime approaches, energy infrastructure, and cross-border threat correlation, as shown by dedicated U.S.-GCC working groups on IAMD and maritime security. The European Union is moving toward collaborative capability development, with 2024 European defense coordination identifying IAMD, electronic warfare, loitering munitions, and a European combat vessel as cooperation areas, all of which depend on resilient sensing and interoperable battle management. BRICS countries present diverse radar demand signals: China, Russia, and India ranked among the top five military spenders in 2025, while Brazil’s SISFRON and South Africa-linked maritime surveillance initiatives show how land-border and coastal security remain central in emerging-economy defense planning. G7 countries are central to surveillance radar innovation because the group includes the United States, Canada, the United Kingdom, Germany, France, Italy, and Japan, all of which are investing in air defense, civil radar sustainment, maritime surveillance, or allied interoperability. NATO remains the most important interoperability driver: its 2025 IAMD policy places air surveillance within a common allied framework, while its defense expenditure data show all Allies expected to meet or exceed the 2% GDP guideline in 2025, strengthening the fiscal basis for radar modernization and sensor integration.

The United States is prioritizing radar resilience across civil and defense missions, with FAA modernization focused on aging radar infrastructure and the FY2025 defense budget emphasizing missile-defense activities for Guam, uncrewed systems, and Indo-Pacific deterrence. Canada is advancing Arctic and Polar Over-the-Horizon Radar under NORAD modernization to close domain-awareness gaps across northern approaches. Mexico is expanding national airspace protection through CENAVI and the Sistema Integral de Vigilancia Aérea, reaching 62% airspace coverage in 2024 and using radar-based tracking for illicit aircraft detection. Brazil is focused on vast land-border monitoring through SISFRON and tactical radar use against illegal activities in remote areas, including the Yanomami territory case involving real-time monitoring of suspicious air activity. The United Kingdom, Germany, France, Italy, and Spain are pulled by NATO and EU air-defense requirements, especially the need for interoperable IAMD, eastern-flank readiness, counter-UAS detection, and protection of infrastructure. Russia remains a major driver of surveillance radar urgency across Europe because its military expenditure ranked third globally in 2025 and the conflict environment has highlighted the operational importance of drone, missile, air-defense, and electronic-warfare sensing. China’s radar priorities align with broad military modernization and maritime-airspace control, while India combines continental air defense with coastal radar expansion across islands and coastlines.

Industry leaders should prioritize interoperable radar architectures that can connect legacy sensors, ADS-B, AIS, electro-optical systems, passive RF, satellite data, and command-and-control platforms without locking operators into single-mission workflows. Product roadmaps should emphasize counter-UAS performance, low-altitude detection, cyber hardening, electromagnetic resilience, AI-assisted classification, and modular upgrades for phased-array and multi-function radar. Leaders should also build validation pipelines for AI models, including representative clutter environments, adversarial testing, explainable alerts, and human-in-the-loop controls aligned with NIST and NATO responsible-AI principles. Go-to-region strategies should reflect mission differences: North America requires Arctic and civil-radar sustainment; Europe requires interoperable IAMD; Asia-Pacific requires maritime-air and island-chain surveillance; Latin America requires border and anti-trafficking coverage; the Middle East requires IAMD and maritime protection; and Africa requires cost-effective coastal and fisheries surveillance.

The research approach combines structured secondary research, official policy review, defense budget and expenditure analysis, capability-program mapping, and technology trend assessment. Sources are prioritized in the following order: official government and intergovernmental documents, defense and aviation authorities, recognized security research institutions, standards bodies, peer-reviewed technical literature, and validated regional security publications. Findings are triangulated across multiple source classes to distinguish confirmed modernization activity from commentary, procurement intent, and speculative claims. The methodology excludes market sizing, market share, and market forecasting; instead, it focuses on verifiable capability drivers, mission requirements, policy commitments, modernization evidence, and technology adoption signals relevant to surveillance radars.

Surveillance radars are entering a decisive modernization cycle defined by multi-domain sensing, AI-assisted interpretation, counter-drone urgency, missile-defense integration, and maritime-domain awareness. The strongest opportunities are not tied to isolated radar hardware but to resilient sensor networks that deliver trusted tracks, fused operating pictures, and faster decision support across civil, defense, and homeland-security missions. Regions and groups differ in operational emphasis, yet the common requirement is clear: surveillance radars must be interoperable, cyber-secure, upgradeable, AI-ready, and effective against low-observable, low-altitude, high-speed, and non-cooperative targets. Organizations that align radar innovation with verified mission needs, responsible AI governance, and open integration standards will be best positioned to support the next generation of air, land, sea, and border surveillance.
