Radar elevation angle measurement

A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:

• transmitting one or more signals from a radar towards a reflection structure comprised of individually controlled motors operable to rotate one or more corner reflectors;
• receiving echo signals at the radar from each of the one or more corner reflectors that sequentially transitioned to an ON position based on each of the one or more corner reflectors being sequentially rotated to be in an ON then an OFF positions;
• collecting data associated with the echo signals received from the one or more corner reflectors;
• identifying peak signal values based on the collected data;
• and
• calculating a radar pitch angle of the radar based on the peak signal values.
