摘　　要：提出一种窄带雷达高速多目标检测和运动参数估计方法。利用"Dechirping"加滤波的方法对回波进行分离并且构造每个目标的回波矩阵,接着对每个回波矩阵构造相干相位补偿函数并进行补偿,从而实现信号能量的相干积累,有利于目标的检测。利用估计的多普勒信息可以获得目标的运动参数。仿真结果验证了所提方法的有效性。A method for the detection and motion parameters estimation of the high speed multi-target in narrowband radar systems is presented. The echo is separated by using the Dechirping and filtering, then the echo matrix of each target is constructed. Then a coherent phase compensation function is constructed and is compensated for each target, so that the energy of the target can be accumulated coherently, and it is helpful for target detection. With the estimated Doppler information the motion parameters can be obtained. Simulation resuits show that the proposed method is effective.
