Mutually Comparison of Sub-Optimal Passive Sonar Detection Structures

The two most important sub-optimal detection structures of the passive sonar are considered: the so-called wideband and standard structures. For the both structures is supposed that the useful signal of the vessel noise, on the receiving location, is much weaker then the interference (signal by deep-sea ambient acoustic noise). The sub-optimal structures are synthesized on the basis of optimal detection structure. The idea was to synthesize the sub-optimal structures as optimal structures, but for simplified receiving signal. And so, the wideband sub-optimal structure is a real optimal structure to the receiving signal without narrowband parts. The standard sub-optimal structure is a real optimal structure to the receiving signal that has, besides, the constant power spectral density. The comparison is on the basis of the detection probability values.
