METHOD, SYSTEM AND CALIBRATION TARGET FOR THE AUTOMATIC CALIBRATION OF AN IMAGING ANTENNA ARRAY

摘要

The system is used for the automatic calibration of an imaging array using an evaluation unit. The array transmits signals and receives the signals reflected from a calibration object of known shape. The calibration object provides at least one diffuse reflector. In the evaluation method, position coordinates of the calibration object are entered, and the following method steps are implemented after the measurement of the reflected signals: (i) calculate the reflections of the calibration object, (ii) calculate calibration data, (iii) prepare an image of the calibration object with the use of the calibration data, (iv) determine corrected position coordinates by evaluating the image of the at least one diffuse reflector, and (v) implement steps (i) to (iv) with corrected position coordinates.
