摘要
为了实现光电对抗装备对抗效果的评估,为某型激光导引头仿真模型的子模型建立了四象限探测器模型并进行了数学仿真。提出了快速计算激光光斑落在四象限探测器每个象限的光斑能量的方法,即激光光斑象限能量分割模型,弥补了传统和差电路定向法的不足。结果表明,建立的四象限探测器模型能够模拟四象限探测器的工作过程,并且具有易实现、运算速度快等优点。这对于提高某型激光导引头数学仿真系统的可信度和真实性,以及提高该系统的实时仿真速度是有帮助的。
In order to evaluate the countermeasure effect of the electro-optical countermeasure equipment in the electronic base,the quadrant detector（QD） model was established,which is the sub-model of a certain type laser seeker,and simulated.The spot quadrant energy division model compensates the deficiency of the traditional sum-and-difference circuit method.The simulation result shows that the QD model can imitate the process of the QD,and it has advantages of feasibility and fast computation,which improves the credibility and reality of this type of laser seeker,and the real-time simulation speed as well.
