The problems of the synchroextracting transform method being unable to handle FM signals and being prone to time?frequency feature discontinuity in a strong noise environment are addressed by the construction of a novel rotation synchroextracting chirple...

Since the advent of ?pulse compression? radar, the ?chirp? signal (Linear Frequency Modulation, LFM) has been one of the most widely used radar waveforms. It is well known that, by changing its modulation into a Non-Linear Frequency Modulation (NLFM), be...

It is shown that replacing the sinusoidal chip in Golay complementary code pairs by special classes of waveforms that satisfy two conditions, symmetry/anti-symmetry and quazi-orthogonality in the convolution sense, renders the complementary codes immune ...
