详细讨论了机载海洋激光测深系统最大测量深度与相关因子之间的关系 ,并利用最小可探测信噪比为判据 ,对机载海洋激光测深系统在白天和晚上工作进行了数值模拟 ,通过比较最大测量深度与激光脉冲峰值功率、接收视场角、接收口径和光谱接收带宽等关系 ,确定了系统的主要参量。以确定的参量建立的系统具有白天 4 9m和晚上 6 5m的最大测深能力 ,可完全满足在沿岸带以及岛礁的测量要求
The relationship between the maximum measured depth and the correlation factor of airborne ocean laser sounding system is discussed in detail and the numerical simulation of daytime and nighttime operation of airborne ocean laser sounding system is carried out by using the minimum detectable SNR The main parameters of the system were determined by comparing the maximum measurement depth with the peak power of laser pulse, the receiving angle of view, the receiving aperture and the bandwidth of spectrum receiving. Systems established with defined parameters have maximum sounding capabilities of 49 m at daytime and 65 m at night, fully meeting the measurement requirements of the coastal zone and the reefs
