摘要
针对常规兵器靶场试验中,传统遥测天线由雷达提供引导数据时存在远射程不能全弹道跟踪目标的问题,提出了利用遥测数据流中的GPS等位置信息作为导引数据,引导遥测天线跟踪被测目标的方法,该方法从遥测数据流中实时提取GPS位置信息,利用遥测数据流中的位置信息与理论弹道比较、弹道预测和修正等算法,实时引导天线准确地指向飞行目标。试验表明,这样既解决了接收到的遥测数据质量不高问题,也解决了数字引导方式下雷达提供的导引数据非全弹道问题,实现遥测天线全弹道、精准地指向飞行目标,从而提高遥测接收能力。
In the conventional weapon range testing,the traditional telemetry antenna in the digital guidance data provided by radar can not track target in whole trajectory,a?guidance data using GPS location information in telemetry data stream was presented to guide telemetering antenna.The method extracted real-time GPS location information from the telemetry data stream,using the information and theoretical trajectory comparison,trajectory prediction and trajectory correction,such as real-time accurate guide antenna pointing to flying target.The test showed that the received telemetry data quality was high,the radar data was whole trajectory in digital guide mode,precisely pointed to the flying target at the whole trajectory,so as to improve the ability of telemetry receiving.
