摘要:

针对一般拟合法在处理空-空导弹攻击区这一复杂的非线性函数时所存在的问题,提出多关系式拟合—插值法,降低了拟合阶次。数字仿真结果表明,该方法极大地提高了拟合的精度和速度。

关键词: 空-空导弹攻击区, 最小二乘拟合, 插值

Abstract:

This paper intends to provide accurate air to air missile launch envelopes for the pilots. Based on the analysis of relationships between missile launch envelope and attack conditions, a hybrid method of least square approximation and interpolation is introduced. Simulation results show that this method greatly increases the accuracy of on line launch envelope computation, while the implementation burden is decreased.

Key words: airtoair missile launch envelope, least square app roximation, interpolation
