Efficient digitization of compound analog signals

The problems related to digitization of sonar compound analog sounding signals reflected from a target are considered. With the use of mathematical simulation, it is shown that, in the case of the most efficient Kotel’nikov digitization, errors occur that impede correct correlation signal processing. This difficulty can be overcome via a reduction of the sampling interval by a factor of 2 to 4 relative to the interval proposed by Kotel’nikov.
