摘　　要：针对采用遥测数据包包校验技术判别遥测定位数据有效性时,产生的过度滤除有效定位数据以及无效数据滤除不干净的问题,提出了一种基于DS证据理论的遥测定位数据有效性实时判别方法。利用遥测数据中的定位数据的位置、速度、加速度信息和理论弹道位置、速度、加速度信息,预测遥测定位数据的合理范围,使用DS证据理论原理,直接判断遥测定位数据的有效性,试验结果表明,该方法可以有效地滤除遥测定位数据中的无效数据。Aiming at the problem of over-filtering the effective positioning data and filtrating the unclean invalid data when using telemetry data packet check technology to judge the validity of telemetry positioning data, this paper proposed a real-time method to estimate the validity of telemetry positioning data bases on DS evidence theory, using the position, velocity and acceleration information of the telemetry positioning data as well as the the position, velocity and acceleration information of the theoretical trajectory to forecast the reasonable range of telemetry positioning data, using the DS evidence theory principle to estimate the validity of the telemetry positioning data. Experimental results showed that the error coding in the telemetry positioning data could be effectively filtered by this method.
