title = "Self-Powered 24-GHz Doppler Radar for Building Entrance Monitoring Using Cross Correlation and Envelope Detection",
abstract = "A 24-GHz Doppler radar self-powered by solar energy was designed, fabricated and tested for building entrance monitoring. The implemented RF board includes two 4×4 patch arrays, a voltage-controlled oscillator, two low noise amplifiers, and a six-port structure. The solar energy harvesting system has a fractional open-circuit voltage maximum power point tracking circuit, a boost charger controller, two 90×5×3D 200 mW solar panels, and a main and backup battery. Moreover, a crosscorrelation method to detect activity in the radar range and a novel envelope detection method to determine the target walking direction were developed and tested. The radar system is featured as being flexible and portable. The complete radar system has dimensions of 118mm×45mm×20mm.",
