摘要
为了满足攻击区解算实时性的要求,准确建立了攻击区解算模型,充分考虑导弹发动机点火、舵机延时、过载和视线角等实际限制因素;采用黄金分割的搜索方法得到攻击区近、远距离边界,详细分析了大高度差发射时攻击区的变化情况,采用曲线拟合的方法获得导弹攻击区距离函数.大高度差时攻击区远界的大小仍然主要由发射载机的高度决定.检验结果表明实时解算误差较小,该方法是有效的.
To obtain the real-time calculation of attack area,considering engine＇s ignition,driving delay of rudder and other factors,a mathematic model of computing attack area with limited condition was built.The golden section method was used to find out near attack area and far attack area,and the case of large difference of elevation was analyzed in detail.The attack area function was obtained by curve fitting.Far boundary of attack area is mainly decided by the height of fighter under the conditions of large difference of elevation.The test result has little error,and the proposed method is effective.
