ABSTRACT

According to the two-dimensional spatial relationship model of the relative motion between the missile and the target, on the basis of conventional proportional guidance and extended proportional guidance, a composite guidance method using conventional proportional guidance and extended proportional guidance to switch each other for three-dimensional guidance is proposed. The switching basis is based on the angle between the missile speed direction and the azimuth angle. When the included angle is large, the extended proportional guidance is used, and when the included angle is small, the conventional proportional guidance is used. Thus, the problem of rapid increase of miss distance at the end of conventional proportional navigation can be avoided. The simulation analysis also shows that this method is very effective.
