Radar for Medical Applications

Doppler radar for measuring vital signs has been a research topic in recent years. The noncontact radar method requires neither internal nor external surrogates, but it can provide reliable respiration and heart-beat measurements. With this 120GHz high sensitive radar, it is possible to directly detect and measure the chest wall and abdomen movement.

First prototype of Biomedical Radar. Notice the 3D printed and metal coated main reflector and the pcb board with the radar front-end.

The radar front-end is a TRX_120_01 RFE chip (Silicon Radar GmbH), mounted on a FR4 Printed circuit board

The radar is calibrated using a sphere as a reflector
