Experimental Verification of the Three-Frequency Scatterometer Concept

A new three-frequency microwave scatterometer technique has been conceptualized from theory developed earlier for the parent dual-frequency instrument. The theory for this new instrument predicts a significant improvement in output signal quality and, ultimately, in the accuracy of directional measurements of ocean wave spectra. An attempt to experimentally verify this concept is reported here. The results of the studies indicate that the technique is both practical and effective.
