Airport Surveillance Radar Market to Reach USD 19.21 Billion by 2031, Growing at a Robust 9.3% CAGR

The global aviation landscape is undergoing a massive transformation, driven by a dramatic rise in air passenger traffic, rapid infrastructure development, and an urgent need for heightened defense security. As airports scale up to accommodate millions of more travelers annually, the systems keeping our skies safe must evolve alongside them. At the core of this modern air traffic control (ATC) evolution is the Airport Surveillance Radar (ASR) system.

According to a comprehensive study by The Insight Partners, the global Airport Surveillance Radar Market size is expected to reach US$ 19.21 billion by 2031. This vital safety and infrastructure market is anticipated to register a compounding annual growth rate (CAGR) of 9.3% during the forecast period from 2025 to 2031, up from a base valuation of US$ 10.31 billion in 2024. This growth reflects a global push toward modernizing radar assets to meet stringent safety mandates and seamlessly coordinate dense modern air traffic.

Driving Forces Behind Market Expansion

The impressive trajectory of the Airport Surveillance Radar market is propelled by several critical factors:

1. Exponential Rise in Global Air Traffic

The continuous increase in commercial, private, and cargo air travel remains the primary catalyst for the radar market. As skies grow more congested, air traffic management (ATM) systems must minimize flight delays, prevent runway incursions, and maintain strict separation protocols. Modern digital radar systems allow controllers to monitor aircraft positions with pinpoint accuracy, even during severe weather conditions.

2. Global Airport Expansion and Modernization

To combat airspace congestion, governments worldwide are funding massive airport expansion projects and constructing entirely new greenfield airports. Concurrently, regional airports are being upgraded to handle larger aircraft and higher flight frequencies. These new terminals and runways require sophisticated, multi-layered surveillance networks—such as Primary Surveillance Radars (PSR) for non-cooperative targets and Secondary Surveillance Radars (SSR) for identifying transponder-equipped aircraft—to secure their surrounding airspace.

3. Heightened Focus on National Security and Military Airbase Upgrades

Geopolitical tensions have pushed nations to aggressively upgrade their military airbases. Modern defense strategies rely on high-fidelity surveillance systems capable of detecting advanced stealth assets, unmanned aerial vehicles (UAVs), and low-flying threats. Consequently, the defense sector is emerging as a massive customer for dual-use and ruggedized tactical surveillance radars.

Market Segmentation and Technical Evolution

To understand the market’s inner workings, it is helpful to look at how these systems are categorized and deployed:

• By Product Type: The market is divided into Primary Surveillance Radar (PSR) and Secondary Surveillance Radar (SSR). PSR systems operate by transmitting electromagnetic energy and listening for reflected echoes, detecting any physical object in the sky regardless of whether it wants to be found. SSR systems rely on active communication, interrogating the aircraft’s onboard transponder to retrieve specific data like altitude, identity, and flight status. Together, they create a comprehensive operating picture for air traffic controllers.

• By Application: Systems are deployed across Civil Airports—where the focus is on optimizing high-throughput commercial passenger flows—and Military Airports, which prioritize tactical adaptability, electronic counter-countermeasures (ECCM), and threat detection.

Modern technical innovations, such as solid-state transmitter designs and active electronically scanned arrays (AESA), are progressively replacing older, vacuum-tube-based systems. These newer architectures offer significantly higher reliability, lower power consumption, and drastically reduced maintenance down-time.
