Ground-based synthetic aperture radar (GB-SAR) has been successfully applied to the ground deformation monitoring. However, due to the short length of the GB-SAR platform, the scope of observation is largely limited. The practical applications drive us to make improvements on the conventional linear rail GB-SAR system in order to achieve larger field imaging. First, a turntable is utilized to support the rotational movement of the radar. Next, a series of high-squint scanning is performed with multiple squint angles. Further, the high squint modulation phase of the echo data is eliminated. Then, a new multi-angle imaging method is performed in the wave number domain to expand the field of view. Simulation and real experiments verify the effectiveness of this method.

一种大斜视多角度模式下线性轨道地基SAR宽场成像方法

地基合成孔径雷达(GB-SAR)已成功应用于地面变形监测。但由于GB-SAR平台长度较短,观测范围受到很大限制。实际应用促使我们对传统的线性轨道GB-SAR系统进行改进,以实现更大的视场成像。首先,使用转盘来支持雷达的旋转运动。接下来,以多个斜视角度执行一系列高斜视扫描。此外,消除了回波数据的高斜视调制相位。然后,在波数域中进行了一种新的多角度成像方法,以扩大视野。仿真和实际实验验证了该方法的有效性。
