基手舰艇基线及DGPS的雷达实时标校方法

摘要

In order to improve the measuring precision of shipboard radar calibration, the method of real-time calculating and calibrating radar true value is designed by the revising information and co-ordination based on the vessel baseline data and high precision on DGPS(Difference GPS). And the computation module of true value is proposed. The result of measuring and verification shows, the method is convenience and quick, and it is able to enhance the measuring precision. In addition, due to the method can revise more radar at the same time, so it improves the calibration efficiency of shipboard radar.%针对舰载雷达标校真值测量困难、精度不高等问题,设计了一种利用舰艇基线数据和高精度差分GPS测量信息进行基线修正、坐标变换,实时计算雷达真值并标校的方法,给出了真值计算模型.测试验证结果表明,该方法得到的真值精度高,使用方便、快捷,不受环境制约,且可同时对多部舰载雷达进行标校,有效提高了舰载雷达标校效率.
