摘要: 基于“猫眼效应”激光主动探测技术,是对无人机光电侦察系统实施强激光干扰较为有效的一种干扰手段。根据激光照射“猫眼”目标的回返特性,建立了不同情况下回波强度模型,对典型目标在不同目标反射率、不同激光发射功率、不同激光发散角情况下进行仿真分析。结果表明,仿真结果与理论计算相一致,因此可用于指导未来基于激光主动探测技术的强激光干扰系统设计。

Abstract: Active detection technique based on “cat's eye effect” is an effective means of interference to implement strong laser jamming against drone photoelectric reconnaissance systems. According to the “cat's eye” return characteristics of the photoelectric reconnaissance target, the echo intensity model is established under difference conditions. Simulation analysis is carried out for a typical target in different reflectivity, different laser powers, and different laser divergence angles. The result shows that the simulation results are in accordance with the theoretical model. The conclusions can be used to guide the system design of high-altitude, strong laser jamming system based on active laser detection technique in the future.

Key words: “cat's eye effect”, active detection, photo electric reconnaissance, strong laser jamming, return characteristics, echo intensity
