全向攻击空空导弹发射包线的快速精确拟合

Fast and Accurate Fit of All Aspect Air to Air Missile Envelopes

基于对攻击区的定性和定量分析，提出了一种使用目标进入角与机动过载的复合三角函数作为自变量的空空格斗导弹攻击区拟合方法。使用同样的阶次，较之于传统的纯多项式拟合方法而言，本文的处理方法显著地降低了界外发射概率和失机概率。

Consider that all aspect air to air missile envelopes are symmetrical about center line when target fly nonmaneuverably. And the envelopes drift toward the direction of target flying when target maneuver, a fit method, in which a compound trigonometric function of aspect angle and target maneuvering factor is used as a parameter in polynomial approximation, is introduced to improve the envelopes approximation charactristics. Simulation results show that in the same order of polynomial, above method is more accurate and fast than the polynomial fit.
