Abstract
A design study was carried out of a small, expendable, self-contained laser altimeter for overwater operations at low altitude. A .904 um GaAs laser was used to build a prototype transmitter/receiver at a cost of less than $600 and small enough to fit inside a 5-inch diameter cylinder, 5 inches long. Tests at a height of 120 feet above the surface of a lake resulted in a signal-to-noise ration of 6, and validated the trade-off equation used in the study. A second test model, with design improvements incorporated, is predicted to yield a SNR of over 20 for an altitude of 150 meters.
