运动目标的速度是影响高分辨雷达宽带一维像性能的重要因素之一，在进行高速目标的宽带回波信号处理时须进行速度补偿。该文首先介绍了一般宽带信号混频处理原理，然后根据雷达、目标之间运动关系建立了一个通用的收发模型，基于相关混频处理方法推导出目标运动速度对宽带回波的响应，最后给出了一个简洁的、便于工程实践的速度补偿方法。

The velocity of moving target is one of important factor affecting the performance of wide-band range profile.HRR radar need velocity compensation in wide-band processing the signal of high speed target. Firstly, this paper in troduces the principle of general wide-band signal mixing processing, then a general transmitting/receiving model is established according to the relationship between the movements of the radar and targets. The response of the moving velocity of the target to the wide-band echoes is derived based on the coherent mixing processing method and a brief velocity compensation method which is convenient for the engineering practice is given at last.
