EXPERIMENTAL STUDY ON META-RADAR SYSTEM WITH MILLIMETER WAVES FOR OBSTACLE DETECTION
In this paper, experimental results are presented on meta-radar for obstacle detection with millimeter electromagnetic waves. Using the best adjusted waveguides with coupling factor of minus 90 dB/m and attenuation constant of 4.75 dB/km, one can detect an obstacle of the order of 30 cm cube in the space 10 cm high and 3 m wide. One can evaluate a detectable distance of more than 3 km apart from the transmitter.
