摘要
常用的合成孔径雷达(SAR)大都采用正侧视带状成像的工作方式。斜侧视即斜视SAR,具有比正侧视SAR在实用上更灵活机动的优势。文中从实时成像和保持SAR高分辨力的角度出发,提出一种消除斜视SAR成像固有的方位距离耦合和减小方位高次相位对方位分辨力影响的预处理方法,以实现斜视SAR的高分辨力实时成像。
In conventional SAR,the radar antenna is pointed in a direction pependicular to the velocityveetor of the radar platform,i.e.in the side looking position.Squint mode SAR, also called squint sidelooking strip imaging mode SAR,has important adventages in applicatioris.It can change the squint angle ofradar beams to acquire more than one imageries of the target terrain when the radar platform only once past the area.It has important means to millitary.This paper gives a new method of real time and high resolutionimaging processing for squint mode SAR.
