【摘要】 建立了导弹与目标的三维相对运动模型，分析了目前寻的制导律的一些局限性，提出了新型非线性寻的制导律。在更复杂的交战环境中，将此制导律用于高性能的ＢＴＴ导弹，可望提高制导精度更多还原

【Abstract】 Three dimensional relative motion model of missile and target is established in the paper Some limitation in today’s most homing guidance laws are analyzed In order to overcome the drawback of the linearization near collision course,nonlinear homing guidance law is derived It is suited to high performance BTT missile in more complex combat enviroment and the guidance precision is greatly enhanced \;更多还原
