Standard Coordinate Amending Method in Accuracy Evaluation Flying Test of Tracing Radar

为了分离炮瞄雷达跟踪精度检飞试验中出现的体效应误差,提出一种采用GPS和光电经纬仪的标准值数据修正方法。分析了跟踪雷达精度检飞试验中测角精度统计误差产生的原因,介绍了GPS数据的修正方法,详细给出以光电经纬仪为标准设备的系统误差、随机误差统计的数据处理方案,并以某型雷达精度检飞为实例,对2条检飞航路的一次差进行处理得到对标准值数据修正结果。分析结果证明:该2种方法可以在跟踪雷达精度检飞试验数据处理中有效消除体效应误差,从而提高被试雷达精度统计结果的准确度。

In order to separating the effect error by target measurement in precision evaluating flying test, the amending methods of standard coordinate data acquired by GPS and photoelectric theodolite are presented. The main cause of statistical error of angle measuring precision of tracing radar is analyzed. The amending method of GPS data is introduced. Details are given to the date processing scheme of system error and random error statistics taking the photoelectric theodolite as standard equipment. The data amending result is acquired during the difference treatment of two air routes offering the flying test of certain radar as an example. The effectiveness of the two above-named methods in the effect error eliminating by target measurement and the accuracy improving of precision statistic of tracin radar are testified.
