  • Abstract
    Passive sonar processing generally consists of many concurrent verniers on each beam or channel which are very narrow bands centered at widely separated, independent frequencies sparsely placed across the total search band. Each is analyzed by a fast Fourier transform (FFT) with extremely narrow coefficients. A cascaded frequency domain filter structure that provides such verniers with fewer computations than other methods is described
