双波长复合激光引信

Dual Wavelength Laser Fuze

激光引信在武器飞行弹道中往往受到云雾、高大树木枝叶的干扰,容易使引信误起动。针对这一问题,通过对激光引信所面临的常见干扰如云雾和绿色植被光谱反射特性的分析,利用云雾和绿色植被与目标在光谱反射特性方面的差异,提出在激光引信中选择两个特征波长进行复合探测,依据两种波长激光的反射信号特征差异来鉴别目标和干扰,并从激光引信接收系统分辨率角度,分析了采用0.85μm和3.2μm双波长激光复合探测技术提高引信对弹道环境中主要干扰鉴别能力的技术途径。

Clouds and trees could be main interference to the laser fuze when weapon in it＇s flying,which will trigger the fuze.In order to overcome this problem,according to the analysis about the back scatter characteristic of clouds and trees,which have different spectrum distribution from targets,the characteristic can be used to distinguish the target and clutter.Two kinds of laser having wavelength of 0.85 μm and 3.2 μm are used to improve the fuze performance of resistant to clouds and trees interference.
