Abstract
A position sensing system for a radar array includes a marker located on a portion of an array assembly. The array assembly includes a radar array that rotates about an axis normal to a radiating face of the radar array during operation. An optical sensor detects the marker to sense an angular position of the radar array.
Claims33
A position sensing system for a radar array, comprising:
- a marker located on a portion of an array assembly, the array assembly including a radar array that rotates about an axis normal to a radiating face of the radar array during operation;
- and
- an optical sensor that detects the marker to sense an angular position of the radar array.
A radar antenna system, comprising:
