The Correlational Study on Laser Detection Sensitivity and Scattering Interceptive Range

为研究激光探测灵敏度对散射截获能力的影响，模拟了5种不同探测灵敏度的激光探测模块，利用吸收型衰减片测试模块的探测灵敏度；在典型大气条件及激光源照射场景下，通过外场试验的方式，测试了不同模块的散射截获能力，记录对应的散射截获半径。通过数据分析，得出激光探测灵敏度与散射截获半径间的相关性，试验结果表明：散射截获半径与激光探测灵敏度正相关，即探测灵敏度越高，散射截获半径越大。In order to research the influence of laser detection sensitivity on the scattering interception capability, five laser detection modules with different detection sensitivities were simulated and interfaced with signal processing modules. These modules’ detection sensitivity was tested with absorption type attenuation sheet. The scattering interception radius of these modules were tested and recorded through field experiments under typical atmospheric conditions and laser source irradiation scenarios. The correlation between the detection sensitivity and the scattering interception radius was obtained after data analysis. The results show that scattering interception radius was positively correlated with the detection sensitivity, the higher detection sensitivity, the longer scattering interception radius.
