Method of target command parameter error estimation to midcourse guidance based on radar mutual-detect mechanism

中段接力制导作战是协同作战的一种具体协同模式。提出基于平台间雷达互测机制与导航信息的目标指令参数误差估计模型。根据平台间的雷达互测机制得到的平台量测和两平台惯导设备输出的自身定位信息,在发射平台的传感器局部坐标系中表示出目标和平台的位置坐标,实现多传感器数据位置对准,并对各平台的设备偏差进行估计和补偿,消除系统误差的影响,提高了各平台的传感器测量数据精度。

Midcourse guidance is a specific form of cooperative engagement. The parameter error estimation model presented with radar mutual-detect mechanism and navigation information used. According to the measuration getted from radar mutual- detect mechanism and the navigation information,the position coordinates of target and relay platform have been expressed in sensor local coordinate system of launch platform,and the multisensor data position alignment realized. Based on this,the parameter errors have been estimated and compensated,the influence of system error eliminated,the accuracy of target position command parameter improved.
