| Abstract: | For the precise test of the dynamic performance of SAR antenna stabilization platform on plane, the test system basing on Position Sensitive Detector is applied to test the platform.The test theory of the system in testing slightly rotational angle of SAR antenna, the construction of the test system, the principium of PSD, the hardware and software implement of signal detection and processing system are introduced. The critical technique in PSD testing is solved. The system can precisely measure and evaluate the major technical indexes of antenna platform and its control equipment, especially the dynamic indexes, such as angle location servo loop track precision index etc.High performance automatic test for platform is realized |
