WIGNER DISTRIBUTION APPLICATION IN DIGITAL PROCESSING OF RADAR SIGNALS
Slobodan Simić Bojan Zrnić In this paper it is presented the approach for radar signal analysis using Wigner distribution. Both, simple and composite radar signals with frequency and phase modulation have been analyzed. This paper presents the overview of the signal changing process during impulse compression while receiving by transforming the signal to time-frequency domain.
