Abstract

A Laser Airborne Depth Sounder system (LADS) has been developed in Australia by the Defence Science and Technology Organisation,1' and a commercial version is nearing completion. This system utilizes a frequency-doubled Nd:YAG laser, repetitively pulsed at 168Hz, to determine ocean depth by the time of flight of each pulse. The measurement of depth is limited by the clarity of the water and the ratio of the reflected laser light (signal) to tire ambient light that is collected by the receiver telescope (noise).
