摘要
依据机载蓝绿激光测深脉冲的传输过程,将激光束在海水中向下和向上传输视为二个不同的传输过程,并利用水下激光束传输唯像模型和水下有限尺寸光源的距离定律,建立了机载激光测深唯像雷达方程,该方程可更精确地计算机载激光测深的能力和较全面地分析影响机载激光测淇深能力的诸因素。
On the bests of the airborne blue-green laser depth-measuring Pulse transmiSSion Process and treating the laser light paths propagating downward and upward the sea as different transmission processes, an airborne laser bathymetry lidar equation is obtained through the Phenomenological model of beam spreading in ocean water and the underwater finite source distant law. The depth-measuring capability of a bathymetry lidar is accurately calculated and the factors affecting the depth-measuring caP8bility of a bathymetry lidar are analyzed.
