针对水下目标探测这一难题,设计了基于距离选通技术的水下激光成像系统并进行了相关实验。从实验结果来看,该系统可有效克服激光后向散射并对水下目标进行成像,对于水下目标探测、识别十分有效。 Aimed at the problem of underwater target detection, a underwater laser imaging system based on distance gating technique was designed and experiments were carried out. From the experimental results, the system can effectively overcome the laser backscatter and imaging the underwater target, for underwater target detection, identification is very effective.
