摘要：

The results of experimental and theoretical studies on the propagation and reception of broadband pulsed signals based on pseudorandom sequences are discussed. The features of impulse response functions for reception of signals with different frequency bands and durations of symbols are investigated. Separation of acoustic energy arrivals in the cross-correlation function of the received and emitted signals is investigated in the framework of the normal mode theory for a deep-sea waveguides. The study concluded that a combination of navigation signals with different symbols duration must be used for solving practical problems of autonomous underwater vehicles positioning.
