Design And Application Of The Airborne Jamming Pod Interference Simulator

This paper focuses on a specific project of the airborne jamming pod interference source simulation. This paper has mainly discussed the active jamming and the deception jamming, and made some research on the realization of the technique of interference and the disturbance signal generation. In the active jamming, this thesis mainly discusses the FM noise interference, emphatically the fast digital led frequency technology based on instantaneous frequency measurement (DIFM), which has an advantage of reducing lead time and improving the frequency guided precision.Under the deception jamming mode, it mainly discusses the implementation of deception jamming technology based on digital radio frequency memory (DRFM) as the core. DRFM using 10 bits amplitude quantification system, can reduce parasitic signal effectively, and maximize the consistence of characteristics of the jamming signal and receiving radar signal. When controlled by software in a nacelle interference system, it can realize distance deception jamming, speed deception jamming, distance-speed deception jamming, many false target interference and Doppler noise interference effectively.The designed radar interference simulator in an airborne jamming pod can simulate various functions about the airborne jamming pod and carry out the high-power noise jamming and deception jamming. In time of peace, the jamming pod system is mainly used in a weapon system for anti-jamming performance tests. It can also be used for officers and soldiers to do radar anti-interference trainings. Finally, the test results of outfield proved it effective.
