本文将宽带FMCW发射波形引入近程TR．R2多站雷达系统，利用FMCW雷达信号的高分辨率特点，分析了近程TR-R2系统的目标定位，提出了利用回波信号频谱估计细柱状目标长度的方法，并导出了计算目标长度的解析公式速度矢量在目标探测与分析中，尤其是在近程目标的识别中具有重要的意义．

The FMCW is introduced into short range TR-R2 multistatic radar system and an analysis is given, for locating the geometric center of a thin cylindrical target in short range using the high resolution of the wideband FMCW signal. Amethod and its analytical expressions for calculating the length of the target using echo spectrum are prasented. Taret velocity measeurement is of important significance for target detection and analysis, especially for reconnizing a target in shart range.In this paper, an algorithm for measuring target velocity with TR-R2 system is analyzed for the first time, and formulae for thecalculation of velocity are shown. System performances are discssed and simulated with the present algorithm.
