Claim 11:
12. A radar controller for a vehicle, the radar controller comprising:
a radar having an antenna for interior detection including a plurality of transmit antennas and a plurality of receive antennas, and an antenna for exterior detection including a plurality of transmit antennas and a plurality of receive antennas;
a table storing sensitivity and a detection speed of the radar for each of a rear occupant alert (ROA) mode and a passenger position notification (PPN) mode among interior detection modes and each of a high-speed mode and a low-speed mode among exterior detection modes, the ROA mode, the PPN mode, the high-speed mode, and the low-speed mode being operation modes of the radar; and
a controller configured to enable the antenna for interior detection when operating the radar in the interior detection modes, enable the antenna for exterior detection when operating the radar in the exterior detection modes, and control the sensitivity and the detection speed of the radar based on the table;
wherein the controller enables all transmit antennas and enables all receive antennas provided in the antenna for interior detection when operating the radar in the interior detection modes, and controls the radar to detect a position of a passenger using a full bandwidth; and
wherein the controller enables some of the transmit antennas and enables some of_the receive antennas provided in the antenna for exterior detection when operating the radar in the exterior detection modes, and controls the radar to detect an obstacle using a partial bandwidth.
