The Wigner distribution has been widely used [1–9] for processing of chirps, i.e. transient signals with constant frequency speeds (chirp rates). These signals have the linear variation of the instantaneous frequency in time. The Wigner distribution is suitable for the chirps; the distribution ideally follows [2] the linear frequency variation of the signal without amplitude errors.
