激光目标模拟器能量链模型的建立与分析

激光目标模拟器是激光制导武器半实物仿真系统的一个重要组成部分。它主要是用来模拟随气象条件、目标反射特性以及飞行距离的变化而变化的激光脉冲,为激光导引头提供一个与实际工作环境相接近的回波信号。从理论上论证了这种激光目标模拟器的可行性。依据波长为1 06μm的激光在大气中的传输特性,结合各种外界条件对它的影响,建立了激光传输的能量链模型,为激光制导武器半实物仿真系统提供了理论依据。

Model and analysis of laser target simulator

The laser target simulator is an important component part in the research of laser guided weapon hardware in the loop simulation system. The laser target simulator is to simulate the target return signals whose properties change with the weather factors, the characteristics of the object and the flight distance, and it provides a return signal similar to the actual signal for the seeker. The feasibility of simulating the target return signal is demonstrated in theory. According to the property of 106μm laser transmission through atmosphere and the influences of all kinds of environments on the laser, the laser energy model is developed which provides a theoretical foundation for the hardware in the loop simulation system of the laser guided weapon. 
