Research on Forcast Model of Taget-indicaton Precision for Ship-board Weap on System

针对舰载武器系统中的目指精度预估问题,基于卡尔曼滤波理论导出了目指距离精度、目指方位精度、径向速度精度与目标航向精度的数学模型,结合最小二乘滤波建立了这些指标参数的简化计算公式,并利用仿真航路进行了验证,结果表明简化公式物理含义直观明确,预估误差在合理范围之内,能够为武器系统目指精度指标的确定提供理论依据,同时为目指精度参数的在线预估提供支持。

The mathematic models of forecasting the Precision of taget-indicaton parameters such as distance,bearing and radial velocity and target course,are proposed based on Kalman filtering theory.The responding simplied formula is set up with LSF and WLSF.The formula is verified by simulation sea routes.The results show that the simplied formula is intuitive with clear physical meaning,and the estimated errors are within the reasonable range,it can provide the theory basis for determining the target-indication accuracy index of weapon system,and can support on-line estimation of the taget-indication accuracy index for ship-boarding weapon systems.
