For ground trainer use only. ### Configuration - Software Version: B.9 Part Number: 4079100-0507 ## Function Receiver/transmitter designed for ground training applications, capable of simulating radar signal reception and transmission without flight qualification. Utilizes software version B.9, allowing interaction with radar systems, diagnostic evaluations, and operational training scenarios. Functions within a non-flight environment, providing realistic radar functionalities for educational or simulation purposes. Connects to trainer systems and interfaces for user inputs and control of radar operations. Suitable for technician training and system verification without airborne deployment. ## Platform Designed for integration in ground-based radar simulation and training systems, operating within fixed military trainer platforms interfacing via standard radar signal and control data buses; supports electrical and protocol compatibility with radar systems emulators, providing essential radar signal processing, receiver/transmitter functionality for operator training and system evaluation without flight certification. ## Application A sophisticated IFF (Identification Friend or Foe) radar component operating in Mode 1, 2, 3/A, 4, 5, and Mode S, providing encrypted military aircraft identification capabilities through selective interrogation and response processing. This receiver/transmitter unit integrates with larger air traffic control and military surveillance systems, enabling target discrimination and secure military identification through cryptographic validation. Designed for ground-based training simulations of airborne identification systems, it replicates operational capabilities of airborne transponder equipment without flight certification, allowing personnel to practice radar identification procedures in controlled environments. ## Images - - - -
