Abstract

Range resolution enhancement techniques, or so called super-resolution ranging techniques, are a significant breakthrough in short-range radar imaging. Improving range resolution in a robust stable manner enables a target to be peeled in finer layers and/or the RF specifications of the radar system to be relaxed, which has clear effects on performance improvement and cost reduction. For a radar system using the frequency modulated continuous wave (FMCW) technique and traditional frequency domain techniques for reception, the range resolution is limited by the bandwidth of the transmitted wave. In this paper we propose and investigate a new super-resolution ranging technique. Multiple key performance characteristics including, minimum distinguishable distance between targets, accuracy in absolute positioning and stability in low SNR environments were evaluated using statistical simulations and real measured data. The presented results show that the proposed technique yields improved performance.
