Microwave Power Transfer Based on Moving Target Tracking in High Frame-Rate Camera Images

We implemented a vision-based microwave power transfer experimental system aiming to feed a moving target. Slot cars moving along a set-up course were used as moving objects. The target slot car was successfully detected, tracked, and irradiated by a power-transferring antenna array embedded with a high frame-rate image-signal-processing directivity controller. Experimental results show that the beam tracking provided high received signal power for a longer time at the moving target slot car than a fixed beam.
