摘要
本文通过位置差分全球定位系统(GPS)的定位技术介绍了火控雷达精度试验的方法,并以试验数据为依据,论证了以位置差分GPS(Global Positioning System)定位数据为真值的可行性。实测数据处理结果表明,位置差分GPS定位数据的数据精度量级如下: 相对位置误差小于5m(RMS); 在距离大于25km的情况下,方位误差小于0.2mil(RMS); 目标航向误差小于3mil(RMs); 目标航速误差小于0.1m/s(RMS)。
The method of accuracy test for fire-control radar by means of position differential GPS positioning technique is described in this paper. On the basis of test data, the feasibility of positioning data provided by position differential GPS positioning technique as truth was demonstrated. Processed results of the measured data show that the accuracy of data provided by position differential GPS positioning technique is as following: Relative position error is less than 5m(RMS); The azimuth error is less than 0.2 mil (RMS) as the distance is more than 25km; The heading error of the target is less than 3 mil (RMS); The velocity error of the target is less than 0.1m/s(RMS).
