Abstract
Optical axis of calibration telescope and television on ship-borne radar will jitter in different de-gree along with the antenna state and the amplitude can reach a magnitude of minute. When calibrating ra-dar’ s zero position and shafting with the reverse method,considerable errors will be produced. So in this paper,a method of judging jitter existing or not is put forward,which detects the not-parallel degree in re-verse and positive direction separately between the optical axis of calibration telescope and televisions. In the meantime,the method of calculating optical axis jitters accurately with geodetic results and its model are provided,which meet the precision requirement of calibration. Consequently,the improved data processing model of correlative correction parameters such as pitching zero position, pitching photoelectric deviation and gravity droop error of antenna,etc,is presented while optical axis jittering.关键词
