基于舰载平台的ISAR成像技术研究

针对舰载平台的 ISAR 成像问题,首先对舰载平台目标回波特性进行分析,并提出基于最小熵的运动补偿方法,接着对一个脉组的回波信号进行合成以形成高分辨一维距离像,利用多个脉组数据获取目标的二维图像,最后对试验情况进行了介绍并给出了结论。

Research on ISAR Imaging Technology Based on Ship-Borne Platform

In order to solve the ISAR imaging problem of ship-borne platform, first, the target echo characteristics are analyzed, and the motion compensation method based on minimum entropy is proposed. Then, the echo signal of one pulse group is synthesized to form high resolution Dimensional distance image, and obtains the two-dimensional image of the target by using a plurality of pulse group data. Finally, the experimental situation is introduced and the conclusion is given.
