基于全球定位系统的舰载三坐标雷达动态标校方法

摘要

为弥补舰载作战系统试验中传统三坐标雷达标校方法的不足,提高标校效率,提出一种基于全球定位系统(GPS)RTK模式动态标校舰载三坐标雷达的方法.该方法通过实时录取GPS的定位数据,经过坐标变换和插值修正,给出目标运动的约定真值.对所设计和实现的三坐标雷达标校系统精度的试验检查结果表明,该标校系统满足舰载三坐标雷达的标校工作,同时降低了对环境的依赖性,便于操作,距离误差在4cm以内.%To overcome the insufficiency of traditional calibration method for three-dimensional radar during testing of shipborne combat system, a dynamic calibration method based on GPS RTK mode was proposed. The method could present true value of target' s movement by gathering position data of GPS, transforming coordinate system and interpolation correcting with the data. Through testing the accuracy of a designed three-dimensional radar calibration system, it was verified that the method was easy to apply and less dependent upon the calibration conditions. The test results show that the distance error of coordinate system is less than 4 centimeters and suitable for calibration of shipborne three-dimensional radar.
