成象雷达通常以载机(或卫星)为平台对地面进行地图测绘、战场侦察和监视等,提供地表面目标信息,获取雷达图象,为军用和民用提供重要目标的特征数据,为使雷达图象真实,数据准确,除研究雷达系统特性和地面目标特征外,另一个重要方面,就是必须认真对待雷达成象中的几何失真,即图象畸变。本文正是针对这一问题进行讨论,分析了在机载侧视雷达中由载机姿态变化所引起的图象几何畸变及其补偿。
Imaging radars usually use the carrier (or satellite) as the platform to map the ground on the ground, reconnaissance and surveillance on the battlefield, provide surface target information, obtain radar images, and provide military and civilian with important target characteristic data. In order to make the radar In addition to studying the characteristics of the radar system and the characteristics of the ground target, another important aspect of the image is that the geometric distortion in radar imaging, ie the image distortion, must be taken seriously. In this paper, we discuss the problem and analyze the geometric distortion of the image and its compensation caused by the change of attitude of the aircraft in the airborne side-view radar.
