摘要
分析了无源激光敌我识别系统组成和工作原理;对系统的光束传输过程进行等效,利用激光波长、束散角、峰值功率等激光参数,推导出了基于高斯光束理论的光束传输模型;采取高斯光束衍生的方法,解决高斯光束通过硬边光阑的传输问题;在考虑大气衰减的基础上,仿真计算了激光敌我识别系统工作中回波信号能量密度与系统作用距离的关系,分析了提高系统作用距离的途径。研究结果一方面对于无源激光敌我识别设备的研制具有借鉴意义,另一方面可以为评估无源激光敌我识别设备作用距离提供支持。
The structure of system and work principle is analyzed for passive laser identification of friend or foe （IFF） system in this paper. By equivalent replacing of system laser beams transmission, the laser beams transmitting model basing on Gaussian beams theory is established by laser parameter of laser wavelength, peak power, divergence angle, etc. In order to solve the problem of hard-edged apertures in system, the method that new Gaussian beams derived from original Gaussian beams is adopted. Under the atmosphere attenuation were considered, the relation between energy density of laser echo and system operation range is simulated. The method that could improve system operation range is analyzed. The research result has reference value to the design of passive laser IFF system. On the other hand, the research result provide help for evaluating operation range of passive laser IFF system.
