Secondary Surveillance Radar (SSR) Market Overview
The global secondary surveillance radars market size was estimated at USD 11.5 billion in 2025 and is projected to reach USD 20.7 billion by 2033, growing at a CAGR of 7.6% from 2026 to 2033.
Secondary Surveillance Radar (SSR) systems are used for measuring the distance of targets using the detection of reflections of radio signals. SSR is also used in air traffic control (ATC) and is based on a radar transponder that responds to the incoming signal by transmitting encoded data like identity code, altitude of aircraft etc.

Secondary Surveillance Radar (SSR) Market Dynamics
The major factor driving the rising demand for Secondary Surveillance Radar(SSR) is the growing population, tourism sector and larger number of people travelling from one place to another. The development of 3d technology and transportable radars for air navigation systems and more people travelling resulting in more air traffic are major factors that will drive the Global Secondary Surveillance Radar‘s forecast market.
New Technologies and Innovations are driving the growth of the Secondary Surveillance Radar Market
Raytheon Technologies Corporation also got an offer from the Missile Defense Agency to deliver some support for high altitude defence radars of the UAE. New innovative technologies like 3-D technology and transportable radars are introduced to avoid any plane delays and for detecting air traffic properly.
The absence of transponder or faulty transponder, defence failure of the country, high cost of installation, restrictions in defence agreements are major factors hampering the growth of this market
Secondary Surveillance Radar (SSR) Market Segment Analysis
The Global Secondary Surveillance Radar(SSR) is segmented based on type, application and region and also on product connectivity, a distribution channel.
Based on the type, the Global Secondary Surveillance Radar(SSR) Market is segmented into Traffic Alert and Collision Avoidance System (TCAS), Automatic Dependent Surveillance-Broadcast (ADS-B) and other secondary radars.
Traffic Alert and Collision Avoidance System (TCAS) estimate whether the aircraft enters the TA/RA based on the interrogation of the ATC transponder and then receiving the signal while ADS-B gives the information automatically without interrogation. ADS-B requires no pilot or any external help. ADS-B is Automatic Dependent Surveillance-Broadcast (ADS-B). ADS-B messages can be tracked at a longer range than TCAS. It is expected that TCAS will upgrade ADS-B in future
Based on applications, the Global Secondary Surveillance Market is segmented into civil airports, national security, Defense and space.
Secondary Surveillance Radar (SSR) Market Geographical Share
Based on Region, Secondary Surveillance Radar’s (SSR) are segmented as North America, Europe, Asia-Pacific, The Middle East, Africa and South America.
North America is considered as the largest market for Secondary surveillance radar and even during the pandemic and post-pandemic, it is expected that North America will be the largest market for SSR’s due to the presence of a large number of big companies in the aviation and defence sector along with advanced technology. The USA, Canada are major countries in North America. There was a growing trend in air traffic in the region due to more passengers before the pandemic.

Key Development
- January 2026 – RTX Corporation & Indra Sistemas (Air Traffic Control Radar Modernization Contract)
In January 2026, the U.S. government awarded major contracts to RTX Corporation and Indra Sistemas to supply advanced radar systems as part of a $12.5 billion national air traffic control modernization program. This initiative includes replacing hundreds of legacy radar systems, many of which include SSR capabilities, to improve aircraft identification, tracking accuracy, and safety. The program also integrates next-generation surveillance technologies alongside SSR, reflecting a shift toward hybrid surveillance architectures combining SSR with ADS-B and digital communication systems. - 2025 (Ongoing) – Global Air Traffic Infrastructure Modernization Driving SSR Deployment
Throughout 2025, multiple countries accelerated airport and airspace modernization programs, leading to increased procurement of advanced surveillance radars, including SSR systems. These upgrades are primarily driven by rising air traffic volumes and the need for Mode S SSR and ADS-B integration, which enhance aircraft identification and reduce congestion risks. Market intelligence sources consistently highlight that SSR remains a core component of integrated air traffic management systems, particularly in civil aviation and defense sectors. - 2025 – Increased Defense Spending Supporting SSR System Upgrades
In 2025, rising global defense budgets particularly in Europe and North America supported investments in air surveillance and identification systems, including SSR upgrades for military airspace monitoring. Governments are prioritizing systems that enable secure identification (IFF) and interoperability with NATO standards, reinforcing SSR’s relevance in defense applications alongside primary radar systems.
