Patent abstract
Examples of the present invention include calibration methods for phased array radar apparatus. The calibration methods include an electronic calibration of phase shifters, and compensation for mechanical misalignment. Approaches are particularly useful for automotive radar, and may be used for initial calibration after installation on a factory line, or at later times such as at a service station whenever recalibration becomes necessary.
