Abstract
The two-frequency microwave technique at slanting incidence for the measurement of ocean wave spectra, first proposed by Rucket al. (1972), is investigated in more detail with respect to its applicability in aircraft and space vehicles. It is shown that by carrying out signal processing in the frequency domain the system-inherent signal-to-noise ratio can be increased considerably, making the operation of the system from air- and space-borne platforms feasible.
