摘要： A radar system comprises a first antenna, an additional antenna, a feed port, an additional feed port, a guiding section and an additional guiding section. The first antenna is coupled to the feed port via the guiding section and the additional antenna is coupled to the additional feed port via the additional guiding section. A radar circuit is configured to operate the first antenna independently from the additional antenna in a separated operation mode and to operate at least one antenna coupled to the feed port together with at least one antenna coupled to the additional feed port as parts of a single common antenna in a combined operation mode.

摘要： An electronic device includes a transmission antenna, a plurality of reception antenna arrays, and a signal processor. The transmission antenna transmits a transmission wave. Each of the plurality of reception antenna arrays includes a plurality of reception antennas each configured to receive a reflected wave. The reflected wave is the transmission wave having been reflected. The signal processor detects, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave, displacement of a subject reflecting the transmission wave. The plurality of reception antenna arrays is arranged in different orientations from one another. The signal processor synthesizes the displacement of the subject detected by each of the plurality of reception antenna arrays.
