Wigner distribution\'s cross-terms suppressing for radar signals processing


М.V. Evsikov – Ph.D. (Eng.), Senior Research Scientist, JSC «Concern «VEGA». E-mail:

Cross-terms may be suppressed during calculation of the Wigner Distribution. Separation cross-terms by time and frequency types very simplified its elimination. Window length duration must be twice or more then duration of pulses within input signal. If duration of each pulse is very different or unknown calculations had to repeat for several values of window length. The spectral Window length must be inverse proportional to time Window length. The Wigner Distribution is recommended compute together with Short-time Fourier Transform or spectrogram with the same window length.
