摘　　要：不同类型空中平台协同对导弹进行中段制导时,中制导权在移交过程中容易引起导弹过载的非正常突变,这主要是由目标信息及制导律切换引起的。基于将突变转化为渐变,从而减小过载变化幅度的思路,采用变权系数方法,提出目标信息交接律及制导律交接律算法。目标信息交接律是给出交接平台目标信息加权后的"虚拟目标"信息,制导律交接律则给出交接前后的加权制导律;两种交接律都是逐渐改变两加权项的权系数比重,直到一项权系数为0,另一项为1,实现加权项之间的切换;同时,为确保交接段导弹过载平滑变化,需满足交接段导弹加速度导数存在。最后通过仿真验证了该交接方法的有效性。In midcourse guidance of missile by cooperation of different kinds of aircrafts, abnormal abrupt change of missile overload is easily emerged in the process of guidance handover, which is mainly resulted from the switching of target information and guidance law. Based on the idea of converting the ＂abrupt change＂ to a ＂gradual change＂, thus reducing the variable extent of overload, algorithms for the handover laws of target information and guidance law are proposed by adopting the variable weight coefficient method. Of which, the handover law of target information gives the ＂virtual target＂ information after weighting on the target information from handover aircrafts, while the handover law of guidance law gives the weighted guidance law of that before and after handover. Both the handover laws gradually change the weight coefficients of two weighted terms, until one weight coefficient is O, and the other is 1, thus to realize the switching between weighted terms. To ensure the smooth transform of missile overload in the handover phase, it should be satisfied that the derivative of missile acceleration exists in the handover phase. Finally, simulations are carried out to demonstrate the effectiveness of the proposed handover method.
