Abstract
Devices, systems, and methods are provided for radar elevation angle measurement. A radar elevation angle measurement system may transmit one or more signals from a radar towards a reflection structure comprised of individually controlled motors operable to rotate one or more corner reflectors. The radar elevation angle measurement system may receive 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. The radar elevation angle measurement system may collect data associated with the echo signals received from the one or more corner reflectors. The device may identify peak signal values based on the collected data. The radar elevation angle measurement system may calculate a radar pitch angle of the radar based on the peak signal values.
