US 2016/0365631 A1 · RADAR AND METHOD FOR SWITCHING TO ENABLE ARRAY ANTENNA

Abstract

A radar and a method for enabling array antenna are proposed. The radar includes a transceiver, a multi-input multi-output (MIMO) array antenna, a phased array antenna, and a controller. The MIMO array antenna is coupled to the transceiver and includes first transmitting sub-arrays and receiving sub-arrays. The phased array antenna is coupled to the transceiver and includes second transmitting sub-arrays and the receiving sub-arrays. The controller is coupled to the transceiver and configured to to enable the first transmitting sub-arrays to form the MIMO array antenna or enable the second transmitting sub-arrays to form the phased array antenna.
