摘　　要：针对试验靶场中的高精度多测速系统中,多普勒频率测量数据的误差对飞行目标产生影响的问题,建立了多普勒频率误差对目标定速的影响分析计算模型。通过仿真计算及定量分析得出,其产生的误差将直接影响目标定速结果,且影响量值随时间增加而逐渐变大。此方法可为飞行目标的定速情况提供有效的分析手段,也为提高外弹道数据处理精度提供技术支持。In view of influence of error of Doppler frequency measurement data on flying target in high-precision multi-velocity measurement system of test range,a calculating model was established to analyze the effect of Doppler frequency error on target speed control. With simulation calculation and quantitative analysis,the resulting error has a direct impact on results of target speed and the impact becomes larger as time goes by. The method offers a new technical means to analyze target speed and provide effective technical support to improve the precision of trajectory data processing.
