Abstract


The effects of azimuthal variability on monostatic acoustic backscatter from the seabed were studied. When converted to scattering strength, the monostatic return showed considerable variability as a function of azimuth. The results showed that the backsattering strength measurements were independent of frequency within the statistical accuracy of the data.
