一、引言利用雷达对目标进行成像一直是雷达工程师们所追求的奋斗目标。雷达成像使雷达由目标定位发展到目标识别,是雷达功能的重大变革。因此,是雷达技术的一个新的研究方向。固定式地面成像雷达是指用地面固定雷达对空中、海面活动目标进行跟踪,并对回波信号进行成像处理、显示目标外形。由于雷达固定,目标运动且目标的运动方式多种多样,这就给成像处理带来许多困难。
I. INTRODUCTION Using radar to image a target has always been the goal pursued by radar engineers. Radar imaging has led to the development of radar from target location to target recognition, a major change in radar functionality. Therefore, it is a new research direction of radar technology. Fixed surface imaging radar refers to the ground fixed radar on the air and sea activity targets to track and echo signal imaging processing to display the target shape. Since the radar is fixed, the target is moving and the target is moving in a variety of ways, which presents many difficulties for the imaging process.
