Small-sized underwater object’s detection and its radial velocity and range estimation based on discrete-coded frequency-modulated signal sequence

Abstract: Hydrolocation and underwater object’s detection and radial velocity estimation play an important role in hydro-acoustics. Their area of application varies from marine mammals’ velocity estimation to marine engineering structures’ protection. This article describes a processing method of small-sized underwater objects’ detection and velocity estimation based on discrete-coded frequency-modulated signal sequence. Nowadays, range and radial velocity estimation problem is still relevant, so this article describes the method used to determine these parameters of an underwater object.

Keywords: Doppler effect, complex conjugation, discrete-coded signal, radial velocity
