摘要
视频合成孔径雷达(video synthetic aperture radar,ViSAR)由于能够连续观测目标区域的变化,在许多领域得到了广泛的应用.首先梳理了国内外ViSAR相关的研究动态,分析了 ViSAR高帧率成像以及动目标阴影形成的原理;然后系统地阐述了国内外ViSAR系统及其处理技术的研究进展,对成像算法、运动补偿算法以及动目标检测与跟踪技术等方面的研究进展进行了梳理和总结;最后总结了目前ViSAR相关的发展,并对未来ViSAR技术的潜在研究方向进行了展望.
Abstract
Video synthetic aperture radar(ViSAR)has been widely used in many fields due to its ability to continuously observe changes in the target area.Firstly,the research trends related to ViSAR at home and abroad are reviewed,and the principles of high frame rate imaging and shadow formation of moving targets in ViSAR are analyzed.Secondly,the research progress of ViSAR systems and their processing technologies of both domestical and international is systematically elaborated,and the research progress in imaging algorithms,motion compensation algorithms,and moving target detection and tracking technologies is summarized.Finally,the current developments related to ViSAR are summarized,and potential research directions for future ViSAR technology are discussed.
