TIM E-FREQUENCY ANALYS IS OF PO LAR IM ETR IC VECTOR SIGNAL AND ITS APPLICATION IN RADAR TARGET RECOGN IT IO N

摘要

The time-frequency analysis technology for polarimetric vector signal is discussed in this paper. Considering the particularity of polarimetric vector signal, a series of lime-frequency transforms for this kind of vector signal are presented With these transforms, both the description of its energy property and of its polarization property can be got in time-frequency domain, while using conventional methods, only the former can be got. Then, we apply these new methods to target recognition experiment, and the recognition results show that these new methods have better performance than conventional ones.
