Abstract:

This report is concerned with the mechanization of the SQS-26 Sonar Equipment to provide the facility for target classification with the high range resolution scattering clue. High range resolution can provide an effective means for rapidly classifying sonar targets. Considerable information about the physical properties of sonar targets can be obtained from the facility for comparing the signal strengths received from closely spaced range cells. The regularity of large surfaces on submarines will produce a high degree of correlation of their back scattered signal amplitudes from adjacent high resolution range cells. The random distribution of the discrete scatterers in a fish school will produce decorrelation between their back scattered signals.
