Abstract

Traditional radar imaging has difficulties in imaging moving targets due to Doppler shifts induced in the imagery and limited spatial resolution of the target. We propose a method that uses a multiresolution processing technique that sharpens the ambiguity function of moving objects to remove Doppler induced imaging errors and improves instantaneous resolution. This method allows for instantaneous imaging of both static an moving objects in a computationally efficient manner thereby allowing more real time radar imagery generation.

运动目标的多普勒补偿多分辨率成像方法
传统的雷达成像由于图像中的多普勒频移和目标空间分辨率的限制,在对运动目标成像时存在一定的困难。我们提出了一种利用多分辨率处理技术锐化运动目标的模糊函数来消除多普勒诱导的成像误差并提高瞬时分辨率的方法。该方法允许以计算高效的方式对静态和运动物体进行瞬时成像,从而允许更实时的雷达图像生成。
