摘要
聚束模式是合成孔径雷达常用的工作模式。聚束模式的精度高,在军事上发挥着很大的作用。滑动聚束模式是一种新兴的工作模式,它有着比条带模式分辨率高,比聚束模式成像区域大的优点,因此受到广泛的利用和研究。在此基础上,根据合成孔径雷达的特点,展开了对合成孔径雷达的侦察研究,并比较分析了星载合成孔径雷达工作模式的侦察,仿真实验验证了可行性。
The spotlight mode is a common working mode for spaceborne SAR. It has high resolution, and plays an important part in the military areas. The sliding spotlight mode is a new working mode. It has a higher azimuth resolution than the sripmap SAR and has larger illumination areas than the spotlight SAR. Therefore, whether in military or in civil use, the sliding spotlight SAR takes on a great development. On this basic, according to the surveillance principle, discuss the surveillance study of the spaceborne SAR and compare the difference between the spotlight mode and the sliding spotlight mode. Then, build up the surveillance naodel, and simulate it. And the simulation proves the surveillance feasibility.
