Abstract :
The fast Fourier transform is employed in the design of replica correlation algorithms for application in narrow-band and wide-band active FM sonar. A discrete analog of the narrow-band heterodyne correlator is presented and modified such as to lead to an efficient technique for wide-band FM where several time-compressed references are required.
