an object detector configured to (1) transmit an object detection signal to a field of view FOV) area corresponding to a FOV of the object detector, and (2) generate object information based on the object detection signal transmitted to and reflected from an object present in the FOV area, the object information indicating a position of the object within the FOV area; and

a processor configured to (1) determine an area of interest (AOI) within the FOV area and (2) control the object detector to generate the object information for the AOI,

wherein, to determine the AOI within the FOV area, the processor is configured to identify, based on the object detection signal reflected from the object, a blind area occupied by a fixed object present in the FOV area, and determine a portion of the FOV area excluding the blind area to be the AOI, and

wherein the controller is further configured to control the object detector to perform beam forming of the object detection signal such that that object detection signal is emitted from the object detector only to the determined AOI.
