Abstract
The present invention relates to a radar device for forming multi-beams in multiple channels from reflected waves of a transmitted wave by using a minimum number of antennas. The device has: antennas used for both transmission and reception A–A; transmission/reception switching meansof each antenna; a transmitter; and a receiverfor receiving the reflected waves of the transmitted wave. The ratio of the distance between adjacent antennas Aand Ato the distance between adjacent antennas Aand Aor Aand Ais 1:2. The transmitted signal is transmitted from each of the antennas selected sequentially and the received signal is processed by DBF in a signal processing controller, wherein eleven channels can be implemented by using four antennas and a space for six antennas.
