Calibration to improve weather radar positioning determination

A method of calibrating antenna-position detection associated with a radar system, the radar system including a first gimbal configured to rotate through a range of angular positions and to which an antenna element is coupled, and a first angle sensor configured to detect an angular position of the first gimbal, the method comprising the steps of:

• mounting a second angle sensor to the first gimbal, the second angle sensor configured to detect an angular position of the first gimbal;
• rotating the first gimbal through each angular position of a predetermined set of the angular positions;
• generating a first set of data with the first angle sensor characterizing a detected angular position of the first gimbal at each angular position through which the first gimbal is rotated;
• generating a second set of data with the second angle sensor characterizing a detected angular position of the first gimbal at each angular position through which the first gimbal is rotated;
• determining, with a processing device, a third data set comprising differences, between the first data set and second data set, in detected angular position at each angular position through which the first gimbal is rotated;
• and
• storing the third data set in a memory device electronically coupled to the first angle sensor.
