The secondary surveillance radar market is witnessing steady growth due to increasing investments in air traffic management infrastructure and rising air passenger traffic across the world. Secondary surveillance radar systems play a vital role in identifying, tracking, and monitoring aircraft by communicating with onboard transponders. These systems provide accurate aircraft position and identification information, improving operational efficiency and flight safety.

According to The Insight Partners, the Secondary Surveillance Radar Market size is expected to reach US$ 6.72 Billion by 2034 from US$ 4.04 Billion in 2025. The market is estimated to record a CAGR of 5.82% from 2026 to 2034.

Growing Demand for Air Traffic Management

The increasing number of commercial flights and the modernization of airport infrastructure are major factors driving market expansion. Governments and aviation authorities are focusing on upgrading existing radar systems to support higher traffic volumes and improve surveillance capabilities. Secondary surveillance radar systems help air traffic controllers maintain safe distances between aircraft and manage congested airspaces effectively.

The adoption of advanced surveillance technologies is also supporting the replacement of older radar systems with modern solutions that offer enhanced accuracy and reliability.
