Title:
METHODS AND APPARATUSES FOR RECONSTRUCTING ANGLE INFORMATION
Document Type and Number:
WIPO Patent Application WO2003048689
Kind Code:
A3
Abstract:
Methods and apparatuses for determining angular information from a target. A plurality of sensors on an image plane are used to obtain measured amplitude data. An azimuth and elevation may be estimated using this measured amplitude data. A residual error between the measured amplitude data and calibrated amplitude data may then be determined. The angular information corresponding to the azimuth and elevation at which the residual error is minimized may then be outputted as representing or corresponding to the angular information of the target.
