摘　　要：提出基于比例导引规律的弹道三维仿真方法,利用弹道仿真法计算了紫外告警系统的探测方位角以及规避时间,分析了来袭导弹距离、威胁方向对探测方位角的和规避时间的影响。结果表明:当导弹在一定距离外,探测方位角随导弹距离的减小而增大、随威胁方向的增大先增大后减小,并且飞机以某威胁方向飞行时,告警系统对某距离范围内的导弹探测方位角几乎没有变化,规避时间随威胁方向的增大而减小。The influence of detection aspect angle on the missile plume ultraviolet （UV） radiation is described. General missile guidance law is introduced briefly. Taking the proportional as an example, trajectory simulation solution is given. UV warning system detection aspect angle and evadable time are calculated by trajectory simulation solution. The influence of missile distance, threat angle on the aspect angle and evadable time is analyzed. The conclusion shows： when the missile locates in some distance, aspect angle increases with the decrease of the missile distance. When threat angle increases, aspect angle increases firstly, and then becomes small. When the plane flies with a certain threat angle, the aspect angle almost keeps invariable for the missile in the range of some distance. The evadable time decreases with the increasing of threat angle.
