Abstract: Disclosed examples include a radar system that operates in a first mode and a second mode. In the first mode, the system detects the presence of an object within a threshold range. In response to detection of the presence of the object, the system transitions to the second mode, and the system generates range data, velocity data, and angle data of the object in the second mode. When the object is no longer detected within the threshold range, the system transitions back to the first mode.
