Publication number: 20200057135Abstract: The present invention provides a radar device capable of reducing processing load while arraying receiving antennas in two directions. In the present invention, a transmitting unit (transmitting antenna) transmits an electromagnetic wave. A plurality of receiving antennas 108 receive a reflected wave from an object which reflects the electromagnetic wave, and convert the reflected wave into a first signal Sig1. A plurality of receiving circuits 520 are respectively connected to the receiving antennas 108 and generate a second signal Sig2 from the first signal Sig1. A signal processing unit 103 processes the second signal Sig2. The plurality of receiving antennas 108 are arrayed in a first direction and a second direction crossing the first direction.Type: ApplicationFiled: November 17, 2017Publication date: February 20, 2020Applicant: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Satoshi SASAKI, Akira KITAYAMA, Hiroshi KURODA
