Directional spectrum may be thought of as the distribution of wave energy with respect to frequency and direction. The method of the analysis of data from gauge arrays to obtain directional spectra was obtained for the first time by Barber. A four gauge system arranged in an equilateral triangular pattern with one gauge located at the center was used as the recording array in a wave tank for the wave simulation. Groups of superimpose sinusoidal wave components were passed through the array. The disectional energy spectra were obtained from the wave records and were compared with the true directions of wave propagation. As the spacing of gauges is very important to obtain the optimum directional spectrum, the optimum spacing of the gauges were recommended. In addition, laboratory generated waves composed of two-directional components are analyzed. The results of the analysis fail to recognize the two superimposed directions of the wave component.
