The Surveillance Radar Market has gained strategic importance in the global defense and security landscape as nations intensify efforts to safeguard borders, manage airspace, and ensure maritime domain awareness. Surveillance radar systems deliver critical capabilities for detecting, tracking, and monitoring airborne, surface, and ground targets across varied operational scenarios. As geopolitical tensions rise and defense modernization agendas accelerate, the surveillance radar market size continues to expand in response to evolving requirements for real-time situational awareness and threat detection.

According to industry analysis, The Surveillance Radar Market is expected to grow from 5.3 USD Billion in 2025 to 8.5 USD Billion by 2035. The Surveillance Radar Market CAGR (growth rate) is expected to be around 4.8% during the forecast period (2025 - 2035).. This remarkable forecast underscores the critical role surveillance radar plays not only in defense but also in civil applications such as aviation safety, border security, and critical infrastructure protection.

One of the core drivers behind this Surveillance Radar Market growth is the heightened focus on national security and defense spending. Many countries around the world are increasing their defense budgets in response to complex threat environments and strategic uncertainties. As a result, investments in advanced radar systems with extended range, higher resolution, and enhanced detection capabilities have become national priorities. This is especially true in technologically advanced regions such as North America and Europe, where modernization programs continue to upgrade aging radar platforms with modern digital systems. 

Technological evolution is another key trend shaping the surveillance radar market. The integration of digital signal processing, Active Electronically Scanned Array (AESA) technology, and artificial intelligence (AI) enhances performance in detection accuracy, target tracking, and multi-target engagement. AESA radars, in particular, facilitate rapid beam steering without moving parts and offer superior reliability and adaptability in contested electronic environments. As radar platforms evolve, the integration of machine learning for pattern recognition and sensor fusion for holistic battlefield picture generation continues to redefine system capabilities. 

The industry share of surveillance radar segments is diversified across air, ground, naval, and space applications. Airborne surveillance radars — deployed on fighter aircraft, unmanned aerial systems (UAS), and early warning aircraft — constitute a significant portion of the market due to the critical need for airspace control and early threat detection. Naval platforms also contribute substantially to market share, as maritime nations deploy radar systems for coastal surveillance, anti-ship and anti-air defense, and search and rescue operations. Ground-based radars remain essential for monitoring borders, urban environments, and ground movements. 

The surveillance radar market forecast shows robust demand across multiple regions. North America continues to dominate due to significant defense investments, a strong ecosystem of defense manufacturers, and ongoing radar system upgrades. Europe also commands a major share, driven by collaborative defense initiatives and the need to secure expansive airspaces. Meanwhile, the Asia-Pacific region is poised for rapid growth, supported by increasing military expenditures, expanding domestic defense industries, and regional security challenges that stimulate radar deployments. 

Beyond defense, surveillance radar technologies are increasingly used in civil aviation to support air traffic control and safety. These systems help monitor aircraft movements, ensure collision avoidance, and manage congested airspaces. Weather surveillance radar also plays a critical role in predicting severe conditions and improving public safety, further contributing to market expansion.

The surveillance radar market size is also influenced by the growing need for integrated multi-sensor networks that combine radar data with other detection systems, enabling comprehensive situational awareness in smart cities and critical infrastructure ecosystems. Advancements in sensor network integration and data analytics allow for enhanced threat detection across vast areas, meeting demand beyond traditional defense use cases.

In summary, the global surveillance radar market is positioned for strong growth over the next decade, driven by defense modernization, technological innovation, and expanded applications in civil and homeland security domains. As nations continue to prioritize high-performance surveillance solutions, investments in sophisticated radar systems are set to strengthen long-term market prospects.
