Abstract
This paper investigates the performance of a quadrature mirror filter (QMF) in detecting two low-probability of intercept (LPI) emitter waveforms: a triangular Frequency Modulation Continuous Wave (FMCW) waveform and a P-4 polyphase code CW waveform. Detection performance for signal-to-noise ratios (SNRs) of +10 dB, 0 dB, −10 dB, and −20 dB is examined. Signal features that can be extracted are also quantified. Results indicate that QMF processing can provide good detection of LPI waveforms even in the presence of a moderate amount of noise.
