Abstract
A radar apparatus includes a transmitter configured to transmit electromagnetic waves; 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 respective resolutions of scanning front regions based on the relative velocity of the at least one front object.

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 extract a distance to the at least one front object, and locally adjust a horizontal angular resolution and a vertical angular resolution of steering the electromagnetic waves in scanning the front region based on the distance to the at least one front object, and
- wherein the processor is further configured to:
- control the transmitter to scan, at a first horizontal/vertical angular resolution, a first front region in which a first object moves at a relative velocity within a first relative velocity range and within a first distance range in a direction approaching to the radar apparatus;
- control the transmitter to scan, at a second horizontal/vertical angular resolution higher than the first horizontal/vertical angular resolution, a second front region in which a second object moves at a relative velocity within the first relative velocity range and within a second distance range farther than the first distance range in the direction approaching the radar apparatus;
- and
- control the transmitter to scan, at a third horizontal/vertical angular resolution higher than the second horizontal/vertical angular resolution, a third front region in which a third object moves at a relative velocity within a second relative velocity range higher than the first relative velocity range and within the second distance range in the direction approaching the radar apparatus.

- wherein the processor is further configured to:
- control the transmitter to scan, at a first horizontal/vertical angular resolution, a first front region in which a first object moves at a relative velocity within a first relative velocity range and within a first distance range in a direction approaching to the LiDAR apparatus;
- control the transmitter to scan, at a second horizontal/vertical angular resolution higher than the first horizontal/vertical angular resolution, a second front region in which a second object moves at a relative velocity within the first relative velocity range and within a second distance range farther than the first distance range in the direction approaching the LiDAR apparatus;
- and
- control the transmitter to scan, at a third horizontal/vertical angular resolution higher than the second horizontal/vertical angular resolution, a third front region in which a third object moves at a relative velocity within a second relative velocity range higher than the first relative velocity range and within the second distance range in the direction approaching the LiDAR apparatus.
