Abstract :
This paper examines the performance of the Wigner distribution in detection of two low-probability of intercept (LPI) emitter waveforms: a triangular Frequency Modulation Continuous Wave (FMCW) and a P-4 polyphase code CW signal. Detection performance for signal-to-noise ratios (SNRs) of +10 dB, 0 dB, −10 dB, and −20 dB are examined. Results indicate that time-frequency processing can provide good detection of LPI waveforms even in the presence of a moderate amount of noise.
