It is difficult for missile-borne stripmap SAR to gain the required wide-spread image in the terminal guidance because of narrow beam coverage and short imaging time. To solve the problem,a new scheme of beam scanning is proposed.
针对弹载条带合成孔径雷达(SAR)在末制导阶段由于波束覆盖范围窄和成像时间短,不易获得所要求的大面积图像的问题,提出了一种新的波束扫描方案,并根据导弹在末制导阶段的飞行特点,结合子孔径处理方法,对波束扫描参数进行了理论分析和设计。
