Abstract

The power spectra of linear FM sonar data for two different submarine aspects have been computed. These results are compared with each other and with the power spectra of the associated reverberation data. A different technique for displaying analyzed sonar data has been investigated. This display consists of quadrature sampled data and correlations that are plotted with the computer as projections in three dimensions. The basic shape of the lag window applied to the autocorrelation dominates the shape of the Cepstrum. A good solution to this problem is found to be a clipped cosine bell.
