摘要
提出一种利用布里渊散射激光雷达进行空中目标探测的方法。该方法通过测量空中目标散射回波的频移来发现和追踪目标,具有高灵敏度、高信噪比等优点。本文还设计了基于F-P标准具的ICCD影像探测系统,该系统具有高分辨率时间门控功能和时序控制功能,可实现距离(高度)精确扫描。通过对F-P标准具的自由光谱范围等参数的精确设计,可实现对其对六角铁氧体、铝、高压气体等的特征散射光谱的探测。
A method about the detection of target in air using Brillouin scattering laser lidar is introduced in this paper.The target will be found and followed by detecting the wave shift of its back scattering.This method has the advantage of higher sensitivity and SNR.A detecting system of ICCD imaging technique based on Fabry-Perot etalon is designed through theory analysis and experiment in lab.This system with the function of controllable gate and sequential control can scan subject in distance.The scattering spectra of subject made of（Zn1-xCox）2-W,Al,Fe will be detected through the accurate design of FSR of Fabry-Perot etalon.
