中文摘要：

给出了空空导弹发射包线快速计算的方法和公式。该算法在将导弹模型简化为二维模型的基础上,结合对目标运动的一定假设,对导弹发射包线进行快速模拟。同时,采用三自由度模型、六自由度模型和快速计算方法来模拟导弹发射包线,并对三种方法的精度和速度进行比较。仿真结果表明：提出的快速计算方法虽然降低了一定的精度,但计算速度快、时间短,达到了整个火控系统的精度要求,同时也满足了系统的实时性要求,这点对空对空作战十分有利。

英文摘要：

This paper gives a fast calculation method and formulae of launch envelope of air-to-air missile.This algorithm is established on simplifying model for two-dimensional model of missile,and develops fast simulation of missile launch envelop,combining with certain assumptions of target movements. At the same time,three degree of freedom simulation,six degree of freedom simulation and fast calculation are used to simulate launch envelope of missile,in order to compare the precision and speed.Research result indicates that： In this paper,though the fast calculation method loses some precision,it has high calculating speed and brief time,and meets the real-time under the premises of meeting the precision of entire fire-control system which is very beneficial for air-to-air combat.
