ESM (Electronics Support Measure) systems intercept radar emissions which are within the operating frequency range of the system. ESM system consists of antennas, front end receiver, receiver sub-system, processor sub-system and display sub-system. Antennas intercepts the RF signals which are given to front end receiver. The front end receiver gives amplified RF and detected video outputs. Amplified RF output is given to DIFM unit which measures the frequency. Video output of front end receiver is connected to the receiver sub-system.
