摘　　要：针对混布雷阵在猎扫雷作战效果评估中评估精度差的问题,采用时变带未建模动态系统对猎扫雷作战过程建模,通过引入带未知时变均值和方差阵的虚拟白噪声来补偿猎扫雷作战数学模型建立过程中简化带来的未知模型误差,并采用鲁棒Kalman滤波器对作战效果进行评估。仿真结果表明,该方法可有效改善Kalman滤波器的性能,对混布雷阵有很好的评估效果,评估过程和评估效果更贴近实际。According to the bad precision of the interweaving mine obstacle in operational effect evaluation of mine-hunting and mine-sweeping, the operational model of mine-hunting and mine-sweeping was established through using time-varying unmodeled dynamics system. The unknown error of math modeling which was predigested was compensated by fictitious noise compensation technique through introducing the unknown time-varying mean and variance matrix,and the robust Kalman filter was used for operational effect evaluation. The simulation research testified that the method can effectively improve the performance of Kalman filter and have good operational effect for interweaving mine. The operational process and effect was much more close to the fact.
