A Study of an X-band FMCW Radar for Small Object Detection

This paper presents the design of the low-cost x-band frequency modulated continuous wave (FMCW) radar for small object detection. The FMCW radar is implemented at the frequency range of 10 GHz (X-band). The horn antenna is designed to construct the array antenna with an antenna gain of 23 dBi. The radar targets are composed of a square wooden post, circular cross-section metal rod and square metal plate. The experiment will be conducted in an anechoic chamber. The experiment results of the three radar targets are illustrated. Also, the moving detection of a square metal plate will be performed. The result showed that the proposed system is efficiently employed to detect small objects.
