Wigner Transform Analysis of Single-Pulse, LFM, and BPSK Radar Signals

This MATLAB code applies the Wigner transform to three radar signal types—conventional single-pulse, Linear Frequency Modulated (LFM), and Binary Phase Shift Keying (BPSK)—to generate time-frequency distributions. The implementation demonstrates how the Wigner transform reveals distinct time-frequency characteristics for each signal type, enabling comparative analysis of their energy distribution patterns. The code includes signal generation, Wigner computation using quadratic time-frequency representations, and visualization of instantaneous frequency variations.
