| Abstract: | This thesis discribes the basic features of scouted Doppler radar si gnal, puts forward the method to measure radar signal Doppler frequency of high - speed moving carrier, and points out that there are Doppler frequency difference s in radar illuminating beam. It also discusses the video-frequency properties o f pulse-Doppler radar signals, and advances a method to handle pulse reduplicat i ng differential in the pulse group and scan amplitude modulation of pulse series . |
