In this work we have designed the radar that uses an ultrasonic sensor and is controlled by an Arduino. Radar can detect and display the value of the distance to the item at a distance of 2 cm to 4 ...

This work introduces a D-band 4TX/4RX distributed multiple-input-multiple-output (MIMO) frequency-modulated continuous-wave (FMCW) radar CMOS transceiver with real-time reference-clock synchronization ...
