摘要：

条带模式、聚束模式和滑动聚束模式是SAR的3种工作模式.系统地论证了3种成像模式的区别,包括在成像几何模型、方位向频率历程、距离徙动、天线扫描速度及方位向测绘带宽度、方位分辨率和回波方程等方面的区别,并通过对3种模式回波的模拟,进一步阐述了三者之间的区别.通过对条带SAR、聚束SAR和滑动聚束SAR的比较,可以看出条带SAR和聚束SAR都是滑动聚束SAR的特例.

关键词: 频率历程, 距离徙动, 滑动聚束

Abstract:

Stripmap mode, spotlight mode, and sliding spotlight mode are the three SAR working modes. We present a comprehensive and systematic study for demonstrating differences among the three imaging modes in imaging geometry model, azimuth frequency course, range cell migration, antenna scanning velocity, azimuth mapping strip width, azimuth resolution, and echo equations. Simulation results further confirm the differences among the three modes. By comparing these three modes, we conclude that stripmap SAR and spotlight SAR can be considered as the two special cases of sliding spotlight SAR.

Key words: frequency course, range cell migration, sliding spotlight
