Application of Hilbert Huang transform a single vector sensor resolution of multi-objective
, Instantaneous power and instantaneous orientation with a clear physical meaning. For the signal processing offers a wealth of information. Second, a priori there is no fixed base HHT is adaptive. IMF is based on the characteristics of sequence data drawn from the local time. Each IMF can be seen as an intrinsic signal oscillation mode. Which corresponds to a target of natural oscillation. Not only can be linear, stationary signal can also be a non-linear, non-stationary signals. And not strictly according to the band to split. Compared with traditional methods. Vector HHT method to better target separation of different signals, in particular non-linear, non-stationary signals. Since most of the actual signal is non-linear, non-stationary. Therefore,[link widoczny dla zalogowanych], the actual signal processing for vector HHT has better results summary, HHT combined with the vector signal processing method of the vector HHT single vector sensor in the case. Has a better ability to distinguish multiple targets [2] [3] Reference �� 10554.543.532.521.5l0.50 Pinghai Hong,[link widoczny dla zalogowanych], Liang Kuo-lung.
