合成孔径雷达光学处理器(OSARP)与普通成像系统不同,它处理合成孔径雷达(SAR),数据片。因此,我们不仅要检测OSARP的成像质量还要检测它的功能。本文提供一种检测OSARP的方法。OSARP的功能是通过检测OSARP各组件的调整量来求得的;OSARP的成像质量是用普通检测靶加位移透镜来检测的。我们使用模拟SAR效据片来检验OSARP处理各种雷达相位历程的能力。最后用真实SAR数据片来检验SAR和OSARP的综合成像质量。用这种方法我们实地检测HG-1型OSARP,实测结果表明这种检测方法是可行的。
Synthetic aperture radar optical processor (OSARP) Unlike conventional imaging systems, it deals with Synthetic Aperture Radar (SAR), data slices. Therefore, we must not only test the imaging quality of OSARP but also test its function. This article provides a method for detecting OSARP. The OSARP function is determined by measuring the amount of adjustment for each component of the OSARP; the imaging quality of the OSARP is measured using a common detection target plus a shift lens. We use simulated SAR effects to test OSARP’s ability to handle various radar phase histories. Finally, real SAR data slices are used to test the comprehensive imaging quality of SAR and OSARP. In this way, we detected HG-1 type OSARP on the spot, and the results show that this method is feasible.
