A detection method of differences of polarization angles between three‐component signals

AbstractI describe a new method of detecting differences of polarization angles, azimuth and elevation angle, between two three‐component signals. The differences of polarization angles are calculated directly from nine cross‐correlations between two three‐component signals. I compare the performance of this method to a conventional method based on a polarization filter, which uses Principal Component Analysis, in a computer simulation. When data length is shorter than a period of a sinusoidal signal, which is used as a signal in the simulation, the new method shows both less dispersion and less bias of errors than the polarization filter does. © 2002 Wiley Periodicals, Inc.
