| Light reconnaissance vehicle radar with full phase coherent pulse Doppler system, Pulse Doppler(PD Radar) radar system is widely used in modern radar. It not only has the speed pulse radar range resolution, also has a continuous wave radar resolution. Target echo Doppler information contained in the signal to achieve separation of target and clutter. It can distinguish between the target echo out in strong clutter.This paper introduces the light reconnaissance vehicle radar works, then use the fuzzy function radar signal design tools, simulation results by fuzzy function typical radar signal waveform analysis of how to design so as to obtain a higher resolution. Followed by a study of radar signal processing. Through simulated radar target echo signals, and in the echo signal is added to the corresponding clutter and noise, with clutter and noise interference, we do pulse compression radar,moving target detection(MTD), CFAR processing(CFAR) and other coherent radar signal processing, filter out clutter, get objective information., so that we can get the information of the target. Use Matlab as a platform, the simulation results of the radar target echo signal of pulse compression, moving target detection and CFAR processing are analyzed.Finally, for light reconnaissance vehicle radar system terminal software, introduced the detailed design process software with VC ++ 6.0 completed the preparation of the software, to achieve the goal of receiving and processing radar terminal software and reporting capabilities. |
