Abstract

The invention relates to the technical field of radar electronic warfare systems, and discloses an airborne radar electronic warfare function performance external field ground test system which comprises a host and a calibration extension set electrically connected with the host. The host is used for acquiring a radar excitation signal sent by the airborne radar electronic warfare system and feeding back a target echo analog signal to the airborne radar electronic warfare system, and / or is used for generating an electronic warfare threat analog signal and transmitting the electronic warfare threat analog signal to the calibration extension set; and the calibration extension set calibrates the electronic warfare threat analog signal and sends the calibrated electronic warfare threat analog signal to the airborne radar electronic warfare system. According to the invention, the problems of complicated equipment, tedious test process, low universality, low portability, low integration degree and the like in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of radar electronic warfare systems, in particular to an outfield ground test system for the functional performance of airborne radar electronic warfare. Background technique [0002] Aircraft radar system (Radar) and electronic warfare system (EW) are important components of aircraft integrated radio frequency sensor system. The main task of the radar system is to complete the aircraft's air-to-air target search, tracking and other functions. The main task of the electronic warfare system is to complete functions such as electronic intelligence collection, threat warning, electronic jamming and anti-jamming. Whether the system can work normally so as to accurately provide pilots with battlefield situation data, threat warnings and electronic jamming anti-jamming measures is an important part of ensuring that aircraft perform combat missions. The current airborne radar system and airborne electronic warfar...
