激光引信目标模拟器的设计及性能分析

Design and Performance Analysis of Laser Fuze Target Simulator

激光引信是制导武器普遍使用的近炸引信,然而在激光引信设计过程中模拟真实激光回波存在一定的困难。目标模拟器是激光引信仿真系统中的一个重要组成部分,它主要是用来模拟随目标反射特性及弹目相对位置而变化的激光脉冲,为激光引信提供一个与实际工作环境相接近的回波信号,便于考核引信在不同情况下的启动性能。本文首先分析激光引信目标回波信号功率模拟方法,并给出了激光引信目标模拟器的组成、软件设计及硬件实现,最后对引信目标模拟器的性能进行了分析。

Laser fuze is a kind of proximity fuze generally used in the field of guided weapon. It is difficult to obtain the real laser return signal. The laser fuze target simulator is an important component part in the laser fuze simulation system. The laser fuze target simulator is used to simulate the target return signals whose properties change with the characteristics of the object and missile-and-target relative loca- tion, and it provides a return signal similar to the actual signal for the laser fuze. In this paper the compu- ting method for the power of signal from target is analyzed, and the hardware system and the sofeware of laser fuze target simulator are given.
