摘　　要：为了消除比例导引法末制导段的各种干扰因素,抑制法向过载的跳动,基于广义卡尔曼滤波多步估计理论,提出了将拦截导弹直接向瞬时遭遇点导引的末制导导引方法,并进行了计算机仿真。仿真结果表明,该方法可以明显消除或减小末制导段比例导引律的各种干扰因素,抑制法向过载的跳动,改善末制导的弹道特性,减小脱靶量,缩短拦截时间。In order to diminish various interferences and jumpiness of over loading for proportional guidance law, based on the generalized kalman filter multi-step estimating theory, a new terminal guidance method was put forward that directly guides the intercepting missile flying to the hitting position. The method here undergoes computer simulation process and the results show that the method can be used to diminish or even get rid of various possible interferences for proportional guidance law, restrain the jumpiness of over loading and improves the ballistic characteristics of terminal guidance to further lower the chance of missing targets and shorten the intercepting time.
