Analysis of Low Probability of Intercept Radar Signals Using the Reassignment Method [PDF]

open access: hybridAmerican 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 ...
