Radar And Interfere With The Integration Of Signals

Radar is very important in modern war, we can say that no radar no modern war. Jammer is also need in modern war, so we need both radar and jammer in modern war. The basement of integrate is that radar and jammer in the same war platform and use the same transmitter.Usually the integration of radar and jammer are based on the conception of"Hardware Sharing", i.e. radar and jammer share the same hardware modules.The"jammer"in this paper is in the wide sense, i.e. it already has the functions of detection and analysis of signal, jamming and deception jamming.The author analyze the case in which the radar functions are added to jammer.Traditionally, only the part of the energy of the jamming signal that enters the jammed radar receiver is useful.The echo of the jamming signal is not used. The information of jammed radar or radar platform in the echo is wasted.The author propose, the integrated system process the jamming signal echo as the radar echo, extracting distance and velocity information of the radar or radar platform from the echo. The jamming signal performs both the functions of jammer and radar. In other words, in the integrated system the radar and the jammer"share"the same signal. This type of signal is called"integrated signal"in the later part of this paper.On the basement of"signal sharing", the random binary phase code, random pulse position modulation signal, random PRI signal and their integrated modulation signals have been researched. Through the analysis of average ambiguity function,we can see their good ability of detection;through the fourier transform of the signals and the PD radar simulation platform we can verify their good ability of disturbance.SAR creates the new times of activate microwave remote sensing.Through half century of development, SAR that use the plane for platform are widely used, SAR that use the secondary planet for platform gain big success.SAR is more and more important in both military affairs and civil domain. So the"signal sharing"has been used in SAR, random pulse position modulation signal, random PRI signal and their integrated modulation signals'ability of imaging and disturbance of SAR have been researched.
