Wave-profile recording by radar from a low-flying conventional aircraft offers a means of rapidly collecting large amounts of oceanographic data over wide areas of the ocean in a relatively short time. A series of radar experiments has been conducted from a laboratory suspended beneath the Chesapeake Bay Bridge. The purpose of the series of experiments was to study the problems of wave-profile recording and to make comparisons with standard radar altimetry. Theoretical and experimental analyses based on the work conducted at the bridge laboratory indicate that target-scintillation noise limits the accuracy of a microwave radar used for wave profiling. However, it has been concluded that a properly designed airborne FM-CW radar can produce ocean-wave recordings of sufficient accuracy for all ordinary oceanographic purposes. The specifications for such a system have been developed. One of the basic requirements has been found to be a broad transmitted spectrum, probably in excess of 100 Mcsec this requirement appears to be independent of the exact form which the radar system takes.
