Abstract
Based on the principle on parabolic and proportional navigation guidance (PAPNG), the required pulse number for trajectory correction was analyzed in detail. Specified trajectory fall angle was theoretically analyzed and simulated. The results show that the bigger specified trajectory fall angle is, the smaller the required pulse number is, moreover the more sensitivity of specified trajectory fall angle, the smaller correction distance of fall point is. The basic law for determining specified trajectory fall angle was put forward. At the earlier stage of trajectory correction, specified trajectory fall angle mainly depends on target point location. According to structure and operation environment characteristics of rocket, specified trajectory fall angle can be determined by using non-linear control system. At the later stage of trajectory correction, specified trajectory fall angle has small effect on fall point, and it can be determined by combining the damage efficiency of tactical guideline.
