Global Journal of Research Engineering, 2022 Low probability of intercept radar signals, which are may times difficult to detect and characterize, have as their goal ‘to see but not be seen’. Digital intercept receivers are currently moving away from Fourier-based techniques and toward classical ...

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 ...

Phenomenology of low probability of intercept synthetic aperture radar via Frank codes
SPIE Proceedings, 2014 This paper investigates techniques for using low probability of intercept (LPI) modulation techniques for forming synthetic aperture radar (SAR) imagery. This analysis considers a specific waveform type based upon Frank codes in providing for the LPI capability via phase shift keying (PSK) modulation.
