摘要： According to one arrangement, a processing device includes a processor (13). The processor (13) is configured to acquire first radar echoes from a plurality of first antennas (1,2), generate a first radar image by calculating a spatial correlation between the first radar echoes represented by complex numbers, acquire second radar echoes from a plurality of second antennas (1,2), generate a second radar image by calculating a spatial correlation between the second radar echoes represented by complex numbers, and generate a third radar image by applying at least one of a first synthesis method by synthesis of pixel values represented by complex numbers or a second synthesis method by image synthesis to the generated first and second radar images.

摘要： According to one arrangement, a radar system (10) includes a plurality of antennas, and a processor (13) configured to drive the antennas. In a case of driving the antennas in a first mode, the processor (13) is configured to cause the antennas to be cooperatively operated, and image an object (10a) based on radar echoes received by the antennas. In a case of driving the antennas in a second mode, the processor (13) is configured to cause a first antenna group (31a) to be cooperatively operated, image the object (10a) based on radar echoes received in the first antenna group (31a), cause a second antenna group (31b) to be cooperatively operated, and image the object (10a) based on radar echoes received in the second antenna group (31b). The second antenna group (31b) is different from the first antenna group (31a).

摘要： According to one embodiment, an antenna device includes a first antenna and a second antenna. The first antenna includes a first substrate and a plurality of first elements. The first substrate includes a first face along a first direction and a second direction. The plurality of first elements are arranged along the second direction. The second antenna includes a second substrate and a plurality of second elements. The second substrate includes a second face along the first direction and a third direction. The plurality of second elements are arranged along the third direction. The third direction crosses a plane including the first direction and the second direction. One of the plurality of first elements overlaps the second substrate in the third direction.
