Abstract: This paper presents the detailed derivation of Convolution Back-Projection(CBP) Algorithm in Inverse synthetic aperture Sonar(ISAS), and the simulation according to real sonar and target characteristics in underwater environment is provided. It is shown that the revised CBP algorithm in near-field condition is a suitable imaging method to underwater target.
