Abstract
This work utilized image recognition technology and beam forming technology to build a phased array with the target tracking and transmitting the microwave with a focused beam. The coordinate position of the target is obtained from the image recognition module and converted into phase information for the phased array. This system was constructed by a 1 × 4 5.764 GHz phased array with four 4-bit phase shifters. The phase shifters formed the focused beam, which requires not only the direction angle of the target but also the transmission distance. Using image recognition, the target position with direction and distance information was estimated. The tracking beam method was evaluated by simulation and actual measurement. The results showed that the focused beam can always be formed to follow the target in real-time. The transfer efficiency of the focused beam was improved greatly than the uniform phase beam within a distance of 50 cm. The response time of the automatic tracking power transmission system is about 100 ms.
