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 we take a general OSARP inspection as an example to explain the method of inspection of an OSARP. We relate the adjustable quantities of each adjustable assembly of the OSARP (Optical Systhetic Aperture Radar Processor) with each characteristic number of a SAR (Synthetic Aperture Radar) data film. The applicable range of the OSARP is obtained by testing the adjustable quantities. The imaging quality of the OSARP is inspected with the general testing targets and a shift lens. The advanced inspection of the OSABP is done wilii the simulated SAR daia films. It is a different way, but "the results are tiie same as tiie former, Finally, the ture SAR data film is processed to whow the oomprehensive imaging quality of the SAR and the OSAEP. Tite expearimentel pictures.and data presented in this paper are for reference only. The experimental results show that the method is applicable.
