激光制导炸弹无源干扰的有效性仿真

Effective simulation on passive jam of laser-guiding-bomb

在无源干扰下,激光制导武器不能进入制导段飞行,或制导段飞行的距离小于保证激光制导武器命中精度所需的最小制导飞行距离时,激光制导武器的命中精度都会下降。利用激光制导炸弹弹道仿真软件,得到了为保证激光制导武器不能进入制导飞行时,激光制导武器无控飞行的最小距离和激光制导武器能够进入制导段飞行,保证其命中精度所需的最小制导飞行距离。最后根据激光测距方程,得到了无源干扰有效性条件。

The hit accuarcy of laser-guiding-weapon（LGW） decreases if the LGW can′t entry guiding flying process,or the distance of guiding flying is shorter than the distance which assures the hit accuarcy of the LGW under passive jam environment.Base on laser-guiding-bomb trajectory simulation system,the minimal no-guiding-flying distance when LGW can not entry guiding-flying process and the minimal guiding distance which assures the hit accuracy of LGW are obtained.The effective condition of passive jam is deduced from laser range-finder-equation.
