Abstract :
The problems of underwater acoustic detection by active sonar are studied. Using a generalized likelihood ratio test, a background reverberation-adaptive detector for targets is derived. The algorithm provides constant false alarm rate performance in locally stationary Gaussian reverberation environments. According to an optimum decision rule, the set of procedures to solve the underwater survey problem by active sonar is given
