A New Algorithm of Signal Decomposition and Its Application in ISAR Imaging of Maneuvering Targets WANG-Yong,JIANG Yi-cheng[J]. Acta Electronica Sinica, 2007, 35(3): 445-449.DOI:
A new algorithm of signal decomposition-Modified Adaptive Chirplet Decomposition (MACD) is presented.The results of traditional Chirplet decomposition are not accurate for a complex signal
and this disadvantage is overcome by extending the Chirplet atoms to nonlinear frequency modulated signal.Then an efficient algorithm of parameters estimation to mono-component elementary function and the decomposition method based on CLEAN technique to multi-component signal is proposed
at last this algorithm is used in ISAR imaging of maneuvering targets
and the quality of ISAR images improves greatly.So the MACD algorithm is valuable in practice
and the results of real data demonstrate the validity of the method proposed.
