摘要
采用激光水中传输的唯像方程 ,对水下探测的信号、散射和信噪比进行了计算机模拟和分析 ,并通过提出的最佳参数匹配算法 ,实现了探测系统获得高信噪比回波的目标 .通过探测实验对接收视场角的匹配选取进行了验证 :在中等清洁水质情况下 ,最佳视场角为 3°左右 ,偏离这个值的选取将导致探测信噪比的恶化 .结果表明 ,针对不同应用环境按该算法进行系统参数的匹配选取有助于获得系统最大探测能力 .
The signal power, noise power and SNR of the laser underwater target detection system (LUTDS) are simulated and calculated based on phenomenological formula. The best matching arithmetic of system parameters is put forward to obtain the echo of a high SNR value. Matching selection of FOV is validated by the detecting experiment, with the result that the best FOV ought to be 3° under the middle cleansing seawater, otherwise the echos SNR would worsen. It is shown in this paper that the best matching arithmetic is very helpful to obtaining the best detection capability of the system under different kinds of water quality.
