摘　　要：以目标多点散射模型为背景 ,提出了FM近程雷达回波混频后多分量信号模型。证明单频信号瞬时频率定义不适合多分量信号。首次提出利用TLS -拓广ESPRIT结合数理统计方法求解多分量信号平均频率。计算机模拟表明 ,该方法用于测距时 ,测试精度高。This paper presents a multi-component frequency modulation (FM) signal model for short-range radar based on the multi-points scattering model of a target, and proves that the method of computing the instantaneous frequency of single frequency is not suitable to the multi-component signal. The method of TLS-ESPRIT combining the mathematical statistics is presented for obtaining the multi-component signal instantaneous frequency (IF). The computerized simulation shows that the method has the high accuracy for measuring the distance.\;
