This paper presents a 5.8 GHz Doppler noncontact vibration-detection radar system with 2X2 patch array antennas and single patch antennas. Two different types of antennas are used on both transmitter (Tx) and receiver (Rx) sides, alternately. An actuator is connected with a 16 cm x 14 cm metal plate and generates a 1 Hz sinusoidal movement with 1 mm peak-to-peak displacement. The system can successfully detect a target's vibration when it is vertically misaligned with the target by 31° anddoi:10.1109/isanp.2014.7026567 fatcat:cfsh67dscjhudd57zg2tkazc4q
