Abstract :
FMCW radar with single antenna causes leakage of transmitted signal into the receiver which can reduce the dynamic range and degrade the receiver sensitivity. One of the greatest challenges in designing continuous-wave monostatic radar lies in achieving sufficient isolation between the transmitter and the receiver. A novel adaptive reflected power cancellation technique in real-time digital signal-processing is proposed to nullify the transmitter leakage at the receiver front-end to achieve high isolation. With the digital implementation, the proposed scheme requires limited hardware and reduced logical elements than the previously reported adaptive digital implementations.
