Abstract


Pulse doppler radar is a kind of full coherent radar system, which USES the relative movement between target and radar doppler effect on target information extraction and processing, has the high speed resolution, has been widely used. In this paper, main work is for pulse doppler radar signal processing/active jamming for modeling and simulation research. This article first briefly introduced the development situation of pulse doppler radar, the definition, principle of work; Secondly, studied the mode of pulse doppler radar signal processing, signal processing model is established, mainly includes: target echo signal model, the orthogonal double-channel processing, pulse compression, moving target detection and constant false alarm processing, etc., and verified the simulation; Again, broadband blocking type of jamming and deception jamming is studied in modeling, simulation results are given and the analysis; Finally, studied the key technology of radar data processing: the first part introduces several commonly used solutions of fuzzy algorithm, and compares the strengths and weaknesses of these methods, the second part introduces the state of PD radar single target tracking under several typical tracking filtering algorithm, carried on the simulation analysis for a given algorithm, and get some conclusions.
