摘　　要：文中对末段修正迫弹脉冲修正技术进行了研究,提出了四象限脉冲修正方案和高频照射脉冲修正方案,分别进行了脉冲发动机组布局设计和脉冲修正策略设计,建立了相应的数学模型;四象限脉冲修正方案由于没有准确的目标方位信息,会造成脉冲推力损失和脱靶量增大;通过使用脉冲发动机提前工作角,高频照射脉冲方案能使脉冲作用力的合力作用在正确的修正方向上,有利于减少脱靶量,提高修正精度。This paper researches the impulse correction technologies of terminal correction mortar projectile, put forward the four quadrant impulse correction scheme and the higher frequency laser flash impulse correction scheme. For each scheme, designed its impulse rockets layout and impulse correction strategy respectively according to the work principle of impulse correction control device, and established the corresponding mathematical model. The four quadrant impulse correction scheme may lead to the losing of thrust and the increasing of miss distance, since this scheme cannot measure the exact target azimuth information. Through using impulse rocket pre-working angle, the higher frequency laser flash impulse correction scheme is able to make the direction of composition of forces acted on the accurate correction direction, it is in favor of decreasing miss distance and increasing correction precision.
