Method for processing a complex wideband signal with parabolic frequency modulation

Abstract. The article describes a signal processing method consisting of a sequence of two parabolic frequency modulation signals. Mathematical calculations of processing such a signal was carried out, and mathematical modeling was performed in the MATLAB environment under two conditions: in the presence of a moving and non-moving target in the water. The method for implementing a method of synthesized signal processing in real time is also provided.

Keywords: Doppler effect, radial velocity, parabolic frequency modulation, broadband signal
