| Abstract: | According to the modern airborne pulse Doppler(PD) fire control radar commonly using the digital signal to process the detected target parameters,this paper brings forward a false Doppler frequency jamming method applied to the airborne active self-defense jammer to destroy the detection of the target parameters,introduces the linearity frequency modulation emitting signal applied by the airborne PD radar,and expatiates the theory to process the detected target velocity by means of the digital signal based ... |
