Geometrical Spreading Correction in Sidescan Sonar Seabed Imaging
Sound backscattered to a sonar from a seabed decreases in intensity with increasing range ( R ) due to geometrical spreading. As a far-range approximation, a geometrical spreading correction of + 30 log R decibels may be applied. A correction based on an accurate estimation of the ar...
