1. An electronic device comprising:
a transceiver; and
a processor operably connected to the transceiver, the processor configured to:
transmit, via the transceiver, radar signals for object detection;
determine 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, determine whether the object is detected beyond a second threshold distance, based on the reflections of the radar signals, wherein the second threshold distance is farther away from the electronic device than the first threshold distance;
in response to a determination that the object is within the first threshold distance and not detected beyond the second threshold distance, determine that a field of view (FoV) of the transceiver is fully blocked by the object, and thereby determine that the transceiver is fully blocked by the object; and
upon a determination that the transceiver is fully blocked, modify a wireless communication operation associated with the transceiver.
