Abstract

In this paper, we address the problem of harmonic radar tag detection in the presence of non-ideal linearisation of radar sensors. Due to extremely low signal levels that are expected from passive harmonic tags, inherent non-linearities of radar sensors coupled with parasitic signal leakage from the transmitter to the receiver constitute major problems for tag detection. We propose a simple parasitic harmonic cancellation approach that takes advantage of the knowledge of the sensor geometry to compensate for the parasitic contribution in the delay domain. Our numerical results demonstrate that applying parasitic response cancellation yields considerable improvement to tag detection performance.
