Analysis of low probability of intercept (LPI) radar signals using the Wigner Distribution [PDF]
, 2004 The parameters of Low Probability of Intercept (LPI) radar signals are hard to identify by using traditional periodogram signal processing techniques. Using the Wigner Distribution (WD), this thesis examines eight types of LPI radar signals.

Analysis of Low Probability of Intercept Radar Signals Using the Reassignment Method [PDF]
American Journal of Engineering and Applied Sciences, 2015 Digital intercept receivers are currently moving towards classical time-frequency analysis techniques for analyzing low probability of intercept radar signals. Although these techniques are an improvement over existing Fourier-based techniques, they still suffer from a lack of readability, due to poor time-frequency localization and cross-term ...
