窄脉冲激光引信对云雾中目标的回波特性研究

Study on Echo Characteristics of Narrow Pulse Laser Fuze on Targets in Cloud

激光引信自身工作特性,使其易受到云雾的干扰,从而引起虚警,因此需要提高激光引信抗云雾干扰的能力。本文利用蒙特卡洛法进行建模,分析了目标在云雾环境下对不同脉宽激光的回波特性,并进行了相关的试验验证。数学仿真与试验结果证明,窄脉冲激光引信可以有效抑制云雾回波,提高引信在云雾环境中对目标的识别能力和抗云雾干扰能力,降低引信虚警。

Due to the working characteristics of laser fuze,it is easy to be interfered by cloud,thus causing false alarm.Therefore,it is necessary to improve the ability of laser fuze to resist the cloud interference.Monte Carlo method is used to analyze the echo characteristics of targets in cloud under different pulse width laser,and carry out relevant tests to verify.The results of mathematical simulation and experiment show that the narrow pulse laser fuze can effectively suppress the cloud echo,improve the fuze’s ability to identify targets in the cloud and anti-cloud interference ability,and reduce false alarm.
