1. A processor implemented object detection method for a vehicle traveling in a confined space, comprising:
determining a first beam pattern and a second beam pattern based on geometric information of the confined space;
detecting first candidate objects based on a first transmission signal emitted to form the first beam pattern using at least one antenna;
detecting second candidate objects based on a second transmission signal emitted to form the second beam pattern using the at least one antenna;
detecting at least one clutter object based on the first candidate objects and the second candidate objects;
detecting a ghost object based on the at least one clutter object; and
controlling an operation of the vehicle based on a result of the detecting of the ghost object.
