Some Noise Suppression, Signal Reception, and Polarization Measurement Properties of Crosscorrelated Antennas

Some recent results concerning the suppression of isotropic unpolarized noise fields obtained by studying the spatiotemporal crosscorrelation functions of dipoles imbedded in the spatial noise field have motivated the investigation of the signal reception properties of dipole arrangements with such noise suppression characteristics. The signal reception problem is approached by considering antenna crosscorrelation which simultaneously includes the spatial properties (i.e., the effective height function) of the antenna along with the temporal processing properties of the crosscorrelation detection process following the antenna array. The analytical techniques used include the antenna height function, crosscorrelation, and coherency matrix representation. The results obtained for a general antenna height function are applied to the specific case of dipole antennas. A technique of polarization measurement for incident radiation is derived by examining the crosscorrelation function expressed in coherency matrix notation when the dipole antenna effective height function is used.
