Short summary
The pointing of scanning weather and cloud radars must be very accurate, to within 0.1°. We present a general method to calibrate the pointing of a scanning radar with an elevation and an azimuth axis. Using the Sun as a reference, we can determine the specific misalignments of the radar pedestal, axes and antenna. Once the misalignments are known, we can correct for them by steering the scanner motors accordingly. We provide recommendations and code to apply this method to any scanning radar.
