Claim 0:
1. A method of calibrating a radar antenna mounted on a rotatable support, said radar antenna being mounted at a predetermined position relative to a reference point on said rotatable support, the method comprising:
receiving reference data indicative of a position of a target element relative to a reference location, and of a position of said reference point on said rotatable support relative to said reference location;
receiving orientation data indicative of at least one angular position of said rotatable support and antenna measurement data indicative of electromagnetic echo signals received by said radar antenna from said reference target element;
determining a measured position of said target element relative to said radar antenna, based on at least a portion of said antenna measurement data;
determining a reference position of said target element relative to said radar antenna, based on said reference data and on at least a portion of said orientation data; and
determining at least one bias value or function associated with at least one of said orientation data or said antenna measurement data, based on a deviation between the determined measured position and reference position of said target element.
