Patent ID: 7991589

Claim:
A storage medium having stored therein executable commands for execution on a processor for processing signal data to determine polarization dependent features therefrom, the processor when executing the commands performing: a) providing relation data indicative of a predetermined expression relating ellipse elements describing an ellipse in three dimensional space to components of a three-component signal with each component corresponding to one of three coordinates in the three dimensional space, wherein each component of the three-component signal is related to one of time and coordinates of a second other space and wherein each component of the three-component signal is for being transformed into one of time-frequency domain and space-frequency domain; b) receiving the signal data, the signal data being indicative of a three-component signal with each component corresponding to one of the three coordinates in the three dimensional space, wherein each component of the three-component signal is related to at least one of time and the coordinates of the second other space, the three-component signal being indicative of a characteristic of one of an object and physical event; c) processing the signal data for transforming each component of the three-component signal into one of time-frequency and space-frequency domain, to provide second signal data; d) determining polarization dependent features using the relation data and the second signal data, and, e) processing the second signal data for dividing each of the transformed components of the three-component signal into a linear and a circular portion.
