Abstract:

Using multi-dimensional linear structure of polarization array receiving data, the polarization domain multiple signal classification (MUSIC) algorithm is suitable for frequency hopping and wide band signals. The MUSIC algorithm for polarization array wave direction of arrival (DOA) estimation can use the multi-linear relationships of the data to reduce the need to search parameters. The complete electromagnetic information received by an electromagnetic vector sensor in a single location can be converted to the received signal under any attitude. Position errors are obtained according reference signals gotten during system usage, instead of dedicated calibration signal source. The system realizes automatic calibration of the array element six dimensional space parameters. The simulation experiment results show that the method is effective.
