摘　　要：多频连续波雷达以其高精度测量性能在常规兵器试验中得到广泛应用,但引入导弹武器靶场后,在弹道导弹主动段跟踪测量中多次出现回波信号异常中断以及测量数据随机误差超差等问题,限制影响了该体制雷达的应用。以某型多频连续波雷达历史测量数据为基础,分析了导弹尾焰的微波衰减及其对测速、测距、测角数据精度的影响。结果表明,导弹尾焰和幅度起伏是导致雷达跟踪测量异常问题的主要原因。最后提出优化雷达布站点位、参数设置以及多站联合测量等应对策略,实现了雷达数据质量和整体参试效果的提升。Because of high-precision measurement capability,the multi-frequency CW radar has been widely used in the conventional weapon test.However,radar echo exception and rough measurement data occur during the boost phase of ballistic missile.Based on historical measurement data,this paper analyzes the microwave attenuation of missile tail flame and the influence on measurement accuracy firstly.The results show that the missile tail flame and the amplitude fluctuation are the main reasons for abnormal tracking measurement.Finally,the solution strategies,including optimal radar position,adaptive parameter setting,and multi-station joint measurement,are presented.Thus the effectiveness of radars is improved.
