激光制导武器光斑形状半实物仿真技术研究

在激光制导武器半实物仿真试验中，其中一个要求就是激光目标模拟器为导引头提供的光斑形状应与其在实战环境下“看到”的一致。根据激光制导武器制导原理，建立了实战条件下激光光斑形状模型，并设计了光斑形状半实物仿真系统。依据仿真相似性原理，建立了仿真条件下的光斑形状数学模型及激光目标模拟器发射的激光束散角数学模型，讨论了照射误差对光斑形状的影响。通过仿真分析证明这些模型是正确的。

Research on Hardware-in-the-loop Simulation Technology for Facular Shape of Laser Guided Weapons

One of the requirements in hardware-in-the-loop simulation test for laser guided weapons is that the facular shape with which the laser target simulator provides the seeker is consistent with the facular shape which the seeker has seen under actual combat condition. According to the homing principle of laser guided weapons, a mathematical model of the facular shape under actual combat is set up,a hardware-in-the-loop simulation system for the facular shape is designed. According to the principle of simulation comparability, a mathematical model of the facular shape under the hardware-in-the-loop simulation condition and a mathematical model of laser beam angle eradiated by a laser target simulator is constituted. The facular shape affected by the irradiation error is discussed. The simulation analysis proved that these mathematical models are correct .
