| Abstract: The proposed sonar detector will be illustrated in two cases: cross-correlator detector, and matched filter detector. In each case, we are interested to the output of the detector when the input signal is noisy free and due to signal contaminated by noise, which is assumed to be Gaussian noise. The complexity in the cross-correlator detector may be solved based on the matched filter structure, because of its less complexity and time calculation. This paper also introduces a digital realization of a modified recursive tapped delay line integrator (transversal filter). Such a designed delay line based on analog techniques has a large size and suffers from instability. The digital implementation of this filter solves many of these problems. This paper also introduces a digital realization of a modified recursive SPMF (Single Pulse Matched Filter) and a digital realization of a modified recursive matched filter. So an introduced optimum sonar detector is implemented based on digital modified recursive matched filter. | ||
