A Miniaturized and High Frequency Response 35GHz FMCW Radar for Short Range Target Detections

A miniaturized and high frequency response 35 GHz frequency modulated continuous wave (FMCW) radar system is presented for short range target detections. The system mainly consists of two antennas, a single chip transceiver and a signal processor. Thanks to our design and integrated techniques, high performance of the system is achieved and also verified by experimental results using our fabricated prototype. Our results show that the detection accuracy of 0.2m can be achieved for 15cm *15cm metal targets within detection distance of 12m, along with the radar system total size of 29mm in diameter, which agrees well with our design.
