探讨了机载单天线SAR对巡航导弹进行探测和成像的方法。首先用条带模式对巡航导弹进行广域搜索,以AMTI抑制地(海)杂波,粗略估计出巡航导弹的大体区域和运动参数,继而用聚束模式对其进行高分辨率成像。

[Abstract]
A method is presented for detecting and imaging a cruise missile with airborne Synthetic Aperture Radar (SAR) technique in this paper. With the method, the ground (sea) clutter in SAR strip-map data is suppressed by AMTI (Adaptive Moving Target Indication) at first. Then the cruise missile is detected and its appearing area, together with its motion parameters are estimated. Finally, a high resolution image of cruise missile is obtained by spotlight mode of SAR.
