Abstract

This paper presents a new software-defined radar with multiple frequency continuous waves (MFCW) and a self-interference cancellation algorithm. The presented radar is implemented as a highly reconfigurable system that is made of a USRP X310, two patch antennas and the GNU Radio software. Most of the radar operations can be configured and controlled by the software. The transmitter and receiver channels are in one radio-frequency frontend of the USRP X310, thus releasing the remaining channels for other purposes. The radar is experimentally evaluated in indoor scenarios, operating at a frequency of 4.25 GHz while transmitting MFCW signals within a narrow bandwidth. Experimental results demonstrate that the implemented algorithm enables the SDRadar to effectively measure short-range targets.
