摘　　要： 针对非合作目标高精度弹道测量问题,提出采用一主三副脉冲体制分布式雷达系统组网测量模式,对系统提供的"多测距多测速"冗余测元采用基于函数约束的测元层数据融合计算方法,通过仿真计算,分析了弹道测量精度,结果表明:在合理布站条件下,如果雷达测元只含有随机误差,则弹道测量精度很高;如果测元存在系统误差,则弹道测量精度有所下降。针对消除测元系统误差,提出了4项修正内容。该文研究工作为今后作战试验条件下雷达组网测试和数据处理提供了参考。 Aiming at the high-precision measurement problem for the trajectory of non-cooperative target, the network measuring model of the 1-master 3-deputies pulse-fashion distributed radar system was put forward. The measurement layer data-fusion based on function restriction was applied to the multi-range multi-velocity redundancy measurement elements supplied by this radar system. By simulation analysis, the ballistic measurement accuracy was analyzed. The results show that under the conditions of reasonable layout,the trajectory measurement accuracy is very high if the radar element contains only random errors. If the measured element contains system errors, the trajectory measurement precision declines. Four amendments to eliminate measurement system error were put forward. The research work provides reference for radar network test and data processing under the future combat training conditions.
