Abstract
A method for radar full blockage detection includes transmitting, via a transceiver, radar signals for object detection. The method also includes determining whether an object is detected within a first threshold distance based on reflections of the radar signals that are received. In response to a determination that the object is detected within the first threshold distance, the method includes determining whether the object is detected beyond a second threshold distance, based on the reflections of the radar signals. The second threshold distance is further away from the electronic device than the first threshold distance. In response to determining that the object is within the first threshold distance and not detected beyond the second threshold distance, the method includes determining that the transceiver is fully blocked by the object. upon a determination that the transceiver is fully blocked, the method includes modifying a wireless communication operation associated with the transceiver.
