摘要
Abstract
Traditional method of ship-borne radar accuracy tests by airplane tracking object can not practice fre-quently,so a new method based on star sensing is presented,in which star sensing data obtained by means of star sensor is taken as comparing data . In this paper the transform formula of star sensor′s optical axis pointingfrom the J2000 . 0 inertial coordinate system to the horizontal coordinate system is deduced . Also,the main fac-tors influencing test accuracy are analyzed . According to the tracked object visible or invisible in star sensor, two different methods of photoelectric deviation correction are advanced . The field tests show that the residualobtained by the method is less than 0 . 3'compared with tests by satellite,which meets the needs of the tests . With this method,not only accuracy tests of ship-borne radar can practice frequently but also the validity and real-time property can be improved .关键词
