A method of sensing the average angular re-distribution of a radar return from the sea surface is described, and the application of this principle to the measurement of sea state from high altitude aircraft or satellites is discussed. The collection of field data with an airborne 52.5 Mcsec pulsed radar system is outlined, and a preliminary analysis of this data is presented. On the basis of this analysis it is tentatively concluded that the angular re-distribution of the radar return at the chosen frequency does not in itself offer a means of unambiguously determining ocean wave heights. By considering other characteristics of the radar return together with angular scattering a useful description of the sea surface may be possible, and such techniques will be considered during a further more detailed analysis of the field data. This work will be described in a subsequent final report on the problem. Author
