摘要
如何利用预警卫星提供的弹道导弹主动段状态信息,以及被动段的预测信息引导预警雷达及时捕获弹道导弹目标,是反导预警信息系统的一项重要功能。为此,需要准确获取目标的状态估计与预测误差。针对单星观测下基于标准模板的弹道导弹主动段状态估计算法,获得了关机点状态参数以及估计误差,为改善状态估计提供了依据。在此基础上建立了预测误差估计模型,为优化设定预警雷达搜索区域奠定了基础。
It is important aspect of the anti-ballistic early warning information system to cue warning radars to promptly capture ballistic missiles by using boost-phase state information and passive-phase prediction information of ballistic missiles provided by warning satellites. To this end,it is needed to obtain the state estimation and prediction error of targets. Based on the algorithm for estimating boost-phase states of ballistic missiles Nominal Profile templates when the single satellite is used for observation,burnout state parameters and estimation errors are obtained,which can be used to benefit state estimation. In addition,the forecast error estimation model is established to form a basis for optimizing the setting of warning radar search region.
