激光主动制导武器的信号特征识别体制研究

Signal Characteristic Identification System Study of Laser Active Guided Weapon

激光主动制导武器有着十分明显的特点,其中之一是重频高、脉宽窄。在对激光雷达信号进行探测时,识别中心频率是十分重要的工作。另一方面,在现代战争中攻击者在攻击大型高价值目标时往往采用同时发射多枚弹药的方式,因此要求探测设备必须拥有识别多批次目标的能力。论述了使用数字信号处理体制识别高重频激光信号的理论基础和设计方法,突破了在时域内不能识别多批次脉冲周期信号的限制,而且系统的抗干扰能力也得到了提高。

Laser active guided weapon have obvious characteristics,one is high repeatition frequency and narrow pulse width.In the course of detecting the laser radar signal,to identify the centre frequency is very important.On the other hand,in modern war,the attacker often launches multi-ammunition at the same time when he is attacking large targets of high value,so the equipment for detection must have the ability of identifying multi-target.This article describes the theory base and design method identifying laser signals of high repeatition frequency by using digital signal processing system,which breaks through the limit that multiple pulse period signal can not be identified in time domain,and the anti-jamming ability of system is improved.
