激光半主动制导武器波门宽度优化仿真研究

针对激光制导武器固定波门易受脉间不确定性累计偏差的影响,实时波门易受激光超前转发干扰的现象,利用单个脉冲不确定性发生概率,建立累计偏差的概率密度分布模型,计算超出典型波门宽度的最大脉冲个数,作为消除脉间不确定性累计误差的固定波门宽度选取原则,利用实时波门内单个脉冲的概率分布密度,建立超前转发干扰模型,仿真不同超前量干扰概率,得出实时波门宽度的选取原则。仿真结果对激光制导武器波门宽度优化设置具有借鉴意义。

Simulation Research on Time-gate Width Optimizing for Semi-active Laser-guided Weapon

Aimed at the problem that to laser-guided weapon fixed-time gate was effected by pulse inter- val accumulated error easily, real-time gate was interfered by leading transmit laser-jamming, the proba- bility density model of accumulated error was established by probability of single pulse uncertainty, the maximal pulse number was calculated, which can overstep time-gate width. This selecting principle of fixed-time gate width can eliminate accumulated error. The leading transmit laser-jamming model was es- tablished by probability density of single pulse, the probability of several leading width was given through simulation and calculation, which can be the selecting principle of real-time gate width. The result can be applied to time gate optimizing for semi-active laser-guided weapon.
