基于ISAR图像的矢量脱靶量算法研究

Research on Vector Target-missing Quantity Algorithm Based on ISAR Image

ISAR作为成像雷达的重要分支,其在军事上的应用越来越受到人们的重视,利用ISAR图像实现矢量脱靶量的测量就是其重要应用之一。在获取ISAR图像的基础上,利用同一帧“画面”将靶修正到其几何中心,弹修正到战斗部中心,并给出了修正方法。通过坐标中心平滑与坐标微分求解遭遇段坐标与速度;求取弹靶的分速度和加速度后给出了遭遇段参数相对距离、相对速度和角度的计算公式与方法,最后进行了参数精度分析。

As an important branch of Imaging Radar, the application of ISAR radar in military affairs is attached more and more importance. This paper describes in detail that the target space position can be determined by acquiring the angle information and taking use of the image from many targets,and the target-missing vector measurement will be achieved.
