摘　　要：用最小二乘拟合与插值相结合的方法对空空导弹的发射包线进行处理，降低了拟合阶次。数字仿真结果表明，该方法不但在平常发射条件下极大地提高了拟合的精度和速度，而且在一些传统方法几乎无法使用的异常情况下仍有较好的结果。This paper intends to provide accurate air to air missile launch envelopes(MLE)for the pilots.To overcome the shortages of conventional methods used to fit the MLE,the hybrid method of least square approximation and interpolation is used.Simulation results show that in normal cases,this method can significantly increase the accuracy and speed of on line launch envelopes computation,and in some cases,such as the target maneuver greatly or our fighter fires missile at low velocity,conventional methods can hardly do it as before,our method still have good results.
