采用宽带线性调频信号能够显著地提高雷达的距离分辨率和抗干扰能力，然而雷达与目标间的相对运动损耗了部分目标回波相参积累能量，影响目标频率向和距离向分辨力。针对以上问题，提出了一种基于改进匹配滤波函数的运动补偿方法，补偿信号回波中的相位误差，实现宽带线性调频信号目标运动运动补偿。实验与仿真结果证明了该算法的有效性。

Broadband linearly frequency modulated signal is taken as a common method to promote range resolution and anti-interference performance of radar. However,the relative motion between radar and target consumes partial target echo coherent integration energy,influences the target range and frequency resolution. To solve these problems,a motion compensation method based on the improved match filter is found. This method achieves Broadband LFM signal target motion compensation based on compensating target echo phase error. Experimental and simulation results show the effectiveness of the algorithm.
