Maneuvering target detection in over-the-horizon radar by using adaptive chirplet transform and subspace clutter rejection.
In over-the-horizon radar (OTHR) target detection, the signal to clutter ratio (SCR) is very low, typically from ~50 dB to ~60 dB. Furthermore, for maneuvering targets, such as aircrafts and missiles, Doppler frequencies of their radar return signals may be time-varying. In this case, the Fourier tr...
