UAV-Radar System for Vital Sign Monitoring

Feasibility and fabrication of components of a life-sign radar system on unmanned aerial vehicle (UAV) has been studied. A signal conditioning circuit has been simulated, fabricated, and tested for data preparation and acquisition. Application such as, vitalsign detection, using UAV in real-time requires wireless transmission of baseband data to the monitoring station. Methods have been devised to achieve this goal. A quadrature Doppler radar has been assembled using two single channel x-band MDU1020 radars. The united radars can avoid null point distortion in physiological monitoring. Examinations were performed with both mechanical targets.
