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。 According to the transmission process of on-board blue-green laser sounding pulse, the laser beam is transmitted downward and upward in seawater as two different transmission processes, and the underwater laser beam is used to transmit the phenomenological model and the underwater finite-size light source Distance law, the airborne laser sounding phenomenological radar equation was established. This equation can calculate the capability of laser-borne depth sounding more accurately and comprehensively analyze the factors that affect the capability of airborne laser ranging.
