Abstract
Texture of sonar images is often used to map seabed sediment classes. Changing the duration of the transmit pulse can introduce an artifact because the backscatter statistics depend on the number of scattering centers simultaneously insonified, and that area can depend on pulse duration. Statistical study of this issue became possible based on a recent paper by Chu & Stanton [1], and an analysis is presented here.
