| 摘 要： | 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49m和晚上65m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。

| Abstract: | The relationship between parameters of airborne laser bathymetry (ALB) and its maximum penetration depth is discussed. The minimum detectable signal-to-noise ratio is taken as the criteria of choosing parameter. The performance of ALB in daytime and nighttime is evaluated, and the relationship between maximum penetration depth and transited peak power, receiver aperture, angle of field-view, and spectral bandwidth is demonstrated. The ALB system with the chosen parameters has a penetrability of 49 m in daytime and 65 m in nighttime. It is matched the requirement of costal charting and rack detection. |
