Abstract
According to one embodiment, a radar system includes a plurality of antennas, and a processor configured to drive the antennas. In a case of driving the antennas in a first mode, the processor is configured to cause the antennas to be cooperatively operated, and image an object based on radar echoes received by the antennas. In a case of driving the antennas in a second mode, the processor is configured to cause a first antenna group to be cooperatively operated, image the object based on radar echoes received in the first antenna group, cause a second antenna group to be cooperatively operated, and image the object based on radar echoes received in the second antenna group. The second antenna group is different from the first antenna group.
Claims11
A radar system comprising:
- a plurality of antennas configured to transmit radar signals and receive radar echoes based on reflected waves of the radar signals;
- and
- a processor configured to drive the antennas in first and second modes according to an object,
- wherein:
- in a case of driving the antennas in the first mode, the processor is configured to cause the antennas to be cooperatively operated and to image the object based on the radar echoes received by the antennas,
- in a case of driving the antennas in the second mode, the processor is configured to (i) cause a first antenna group among the antennas to be cooperatively operated as a first group and a second antenna group among the antennas to be cooperatively operated as a second group, (ii) image the object based on first radar echoes received in the first antenna group, and (iii) image the object based on second radar echoes received in the second antenna group, and
- the second antenna group includes at least one antenna, from among the plurality of antennas, that is not included in the first antenna group.
A radar system comprising:
- a plurality of antennas configured to transmit radar signals and receive radar echoes based on reflected waves of the radar signals;
- and
- a processor configured to, in a case where a distance between an object and the antennas is smaller than a predetermined value, (i) cause a first antenna group among the antennas to be cooperatively operated as a first group and a second antenna group among the antennas to be cooperatively operated as a second group, (ii) image the object based on first radar echoes received in the first antenna group, and (iii) image the object based on second radar echoes received in the second antenna group,
- wherein the second antenna group includes at least one antennas, from among the plurality of antennas, that is not included in the first antenna group.
