摘　　要：To study the measurement of distance under the condition of the frequency modulation (FM) multi component signal of a short range radar, the multi points scattering model of a target, the TLS ESPRIT (total least square estimation of signal parameters via rotational invariance techniques) and the mathematical statistics methods were used. The method of computing single frequency signal's instantaneous frequency (IF) is unsuitable to the multi component signal. By using the method of the TLS ESPRIT combined with the mathematical statistics, the multi component signal's IF can be obtained. The computer simulation has shown that the method has the high accuracy for measuring the distance.研究近程雷达FM多分量信号条件下目标距离测量 .利用目标多点散射模型、TLS ESPRIT和数理统计方法确定平均距离 .计算单分量信号瞬时频率的方法不适合于多分量信号 .多分量信号瞬时频率可以利用TLS ESPRIT结合数理统计的方法获得 .
