Abstract : A coherent, dual-frequency, ocean wave spectrometer radar system for measuring the characteristics of ocean surface gravity waves includes: a transmitter for transmitting a pair of closely spaced, coherently related, microwave frequencies; a receiver for receiving and separating the radar-return signals of the dual-frequency channels; a frequency shifter for offsetting the doppler spectrum of each radar return signal; and a multiplier for multiplying the radar-return signals of the dual-frequency channels to obtain a Bragg resonance condition indicating the presence of a particular gravity wave frequency on the ocean surface.
