Laser Wave Estimation. Revision

Abstract

A contract was awarded for the exploration of the potential of an airborne laser for the estimation of wave height. The approach taken was to reproduce old results. It soon became apparent that the simple and economical three or four state models used in earlier work were inadequate and a full fifteen state model for a P3C aircraft was employed. The results obtained using this model. The results of varying wind gust standard deviation, wind gust correlation time, and the standard deviation of combined wave height and measurement error are described. As long wave lengths, characteristics of deep ocean, were also of interest, a model variation was employed to separate wave height and measurement error. The effect of varying pulse repetition rate and beam rotation rate are discussed. Keywords: ATTALT 8 Computer program. (JHD)
