Abstract
A detection device for detecting an OUD (Object Under Detection) includes a first antenna element, a second antenna element, a first transceiver, a second transceiver, a first circulator, and a second circulator. The first transceiver transmits a first electromagnetic signal through the second circulator and the second antenna element to the OUD, and then receives a first reflective signal through the first antenna element and the first circulator from the OUD. The second transceiver transmits a second electromagnetic signal through the first circulator and the first antenna element to the OUD, and then receives a second reflective signal through the second antenna element and the second circulator from the OUD.
