2x2 MIMO FMCW Radar RF Shield

This is a radar Arduino shield was designed at Kennesaw State University and based on the MIT coffee-can design. There is a microwave VDC, power splitter, mixer, three amplifiers, and two SPDT antenna switches. The shield board is designed for the host microcontroller to control the switches through GPIO outputs, utilize a GPIO output to modulate and an analog input to digitize the IF.
