  • Patent number: 11536799
    Abstract: An electronic device capable of reducing a process associated with a radar search is provided. The electronic device DEVa has a transmitting linear array antenna TXA, a receiving linear array antenna RXA, and a control circuit CTLU for controlling the transmitting linear array antenna TXA and the receiving linear array antenna RXA. The transmitting linear array antenna TXA includes a plurality of transmission antennas TXr[1] to TXr[4] arranged along the Z direction, and transmits a transmission wave. The receiving linear array antenna RXA includes a plurality of reception antennas RXr[1] to RXr[4] arranged along an X direction orthogonal to the Z direction, and receives a reflected wave of a transmission wave.

  • Patent number: 11199620
    Abstract: A radar device is provided which is capable of highly accurate distance calculation by a simple method. The radar device includes: a transmission circuit which transmits radio waves; an adjustment circuit which adjusts transmission angles of the radio waves transmitted from the transmission circuit; a reception circuit which receives plural signals which are the radio waves transmitted, based on adjustment made by the adjustment circuit, from the transmission circuit and respectively reflected from an object; and a signal processing circuit which, by processing the received signals, calculates a distance to the object. The signal processing circuit includes a buffer which stores signal strength data on the signals received by the reception circuit, the received signals respectively corresponding to the transmission angles, and a correction circuit which performs correction processing on equidistance-based portions of the signal strength data on the received signals stored in the buffer.
