| 摘 要： | 由于目标机动时间常数会对拦截导弹的性能产生重要的影响,且一般基于目标机动动态考虑的制导律都假设这一常数是已知的,在实际的拦截情形中并不合理.针对这两点,本文采用成型滤波器表示目标的随机机动策略,对原系统的状态进行扩展,并利用扩展后的系统构建多模型自适应估计器的成员滤波器,以实现对于目标机动时间常数的在线估计.仿真结果表...

| Abstract: | The target maneuvering time constant takes the important effect on the performance of interception missiles,but it is not appropriate to make constant assumption of this time constant as some literatures that did in actual interception scenarios.Based on the unknown assumption of this time constant,the shaping filter method is adopted to model the random maneuvering strategy of target and extends the original system states.The elemental filters of a multiple model adaptive estimator based on the extended sy... |
