本文以一个通用合成孔径雷达光学处理器(简称OSARP)的检测为例,来说明OSARP的检测方法。给出OSARP的每个可调部件与合成孔径雷达(简称SAR)数据片的各特征参数间的关系,通过测量调整量求得OSARP的适用范围;用普通检测目标加位移透镜,来检测OSARP的成像质量。同时用模拟的SAR数据片,以另一种方法对OSARP做检测,结果相同。最后处理了真实SAR数据片,用来展示SAR和OSARP的综合成像质量。文中给出一些实验照片和数据,结果表明,本检测方法是可行的。
In this paper, a common synthetic aperture radar optical processor (OSARP) detection as an example to illustrate the detection of OSARP. The relationship between each adjustable component of OSARP and the characteristic parameters of Synthetic Aperture Radar (SAR) data slice is given. The scope of application of OSARP is obtained by measuring the adjustment amount. The normal detection target plus displacement lens is used to detect the OSARP Image quality. At the same time with the simulation of the SAR data sheet, another way to OSARP do the test, the same result. Finally, the real SAR data was processed to demonstrate the integrated imaging quality of SAR and OSARP. The paper gives some experimental photos and data, the results show that the detection method is feasible.
