电视制导武器上摄像机的视场角比较小,弹体稍有扰动,都会造成目标移出视场以外。因此希望在电视制导过程中,一方面目标视线能够保持稳定,另一方面要有足够大的攻击落角。为了实现这两方面的要求,需要设计专门的导引律。以最优控制理论为基础,把命中落角作为系统的终端约束条件,对目标机动情况下的最优导引律进行推导求解。最后以所求解的导引关系式进行仿真攻击,结果验证了该方法可以较好的抑制视线偏转速度和实现约束落角。

Because the visual angle of camera is small, targets will be out of the visual field when the TV-guided weapon is disturbed. In the process of TV-guided, we hope that the line-of-sight will be steady and the terminal angular constraint can be big enough. For the two side demands, we need design special guidance law to carry them out. It has worked out optimal guidance law which based on the optimal control theory and the dive angle restriction of moving targets. Some simulation contrasts have been done in order to prove the guidance law which has been worked out has fairly good capabilities on restraining sight defluxion speed and restricting dive angle.
