The most common type of sounding signals of sonar systems are broadband linear-frequency-modulated signals (LFM). Due to the use of such signals it is possible to increase the range and resolving power of hydroacoustic devices, but this does not solve the problem of mutual interference of pulses. One type of broadband signals are chaotic oscillations, which theoretically are able to become an alternative to chirp signals due to increased resistance to crosstalk. The paper compares chaotic and chirp signals by simulating their passage in an aqueous medium. Chaotic signals generated by systems with different numbers of basins of attraction are investigated. The study shows that chaotic signals are more resistant to mutual interference, and also experience less attenuation when propagating in an aqueous medium compared to the types of signals currently used. The stability of chaotic broadband signals to interference and attenuation correlates with the number of basins of attraction of the attractor of the generating chaotic system. Based on the results of the work, it can be concluded that the chaotic signals are used as probing pulses of sonar systems.

Keywords: linear-frequency modulation, active sonar, cross-talk problem, simulation, hydroacoustics, chaotic system, dynamical chaos, wideband signal, basin of attraction, correlation analysis
