1. A radar apparatus comprising:
a transmitter configured to transmit electromagnetic waves, the transmitter being configured to steer the electromagnetic waves to scan a front region;
a receiver configured to receive electromagnetic waves that are reflected; and
a processor configured to extract a relative velocity, with respect to the radar apparatus, of at least one front object based on the electromagnetic waves received by the receiver,
wherein the processor is further configured to locally adjust a horizontal resolution and a vertical resolution of steering the electromagnetic waves in scanning the front region based on the relative velocity of the at least one front object, such that the horizontal resolution and the vertical resolution are increased in an area in which a front object of a higher relative velocity is present and are decreased in an area in which a front object of a lower relative velocity is present, and
wherein the processor is further configured to extract a distance to the at least one front object, and locally adjust the horizontal resolution and the vertical resolution based on the relative velocity of the at least one front object, and further based on the distance to the at least one front object.
