Airborne fire control radar is the main fire guide unit of warcraft/fighter. So in the airborne EW field, airborne fire control radar is the main counter object. Identify the work mode of airborne fire control radar is the core work and most difficulty part. In this paper, the basic work principle and wave features of the airborne fire control radar are analyzed. By the data analysis of airborne fire control radar’s work status, it introduces the means to recognize the operation mode of the airborne fire control radar and the Formation of aircraft. This method can identify the scan, tracking and SAM status of airborne fire control radar correctly through anechoic chamber radiation test verification. The test results verify the method is available.
