Design considerations in TR Module for SSR application

The Secondary Surveillance Radar (SSR) system is a critical requirement for any airborne surveillance platform, ensuring secure and reliable identification of aircraft in both civilian and military operations. The advanced capabilities of Active Electronically Scanned Array (AESA) technology can enhance SSR performance by offering improved accuracy and sensitivity, faster response times and improved reliability. However, designing a Transmit/Receive (TR) module for AESA-based SSR applications must comply with International Civil Aviation Organization (ICAO) standards to ensure seamless integration with global air traffic management systems. This paper explores key design considerations for TR modules to be deployed in AESA of SSR System.
