一种盲区方案飞行控制方法

为削弱成像导引头制导盲区对导弹命中点性能的不利影响，分析了盲区舵偏角取值对弹道参数的影响，提出了导弹在末端盲区内按舵偏角方案进行方案飞行的控制方法，并讨论了盲区舵偏角方案的选取准则，给出了4种可行的盲区舵偏角方案，进行了仿真验证与综合比较，并对其中效果较好的2种规律进行了优化. 仿真结果表明，与将盲区舵偏角取为常值的传统方法相比，该方法可有效地提高命中精度，减小命中点的攻角与法向过载. 

A Program Flight Control Method Applicable for Blind Area

In order to weaken the negative influence of imaging seeker blind area on the impact performance, the effect on trajectory parameters from rudder angle was analyzed, and a control method based on rudder scheme was proposed. Based on this method, the selection principle of the rudder scheme was discussed, and four feasible variation rules were given to simulate and compare with the effect of the situation when the rudder angle was assigned as a constant in blind area. Then the better two in the four variation rules were optimal designed to achieve better effect. Results of simulations illustrate that the method can improve the hit accuracy of missiles, and decrease the angle of attack and normal overload of the impact point.
