An enhanced super-resolution wavefront extraction algorithm for wideband FMCW radar systems

摘要

In this paper a novel super-resolution wavefront extraction algorithm is introduced that merges the advantages of the efficiency correlation techniques based on [1] and super-resolution ability of DCM techniques [2]. The introduced ADCM algorithm is based on the correlation method DCM, but in contrast this algorithm uses a set of weighted differently shifted reference pulses. Due to the clustering of wavefronts the computational effort of the wavefront extraction is optimized. In the herein used set-up a low-cost, single chip radar operating from 57 GHz to 64 GHz is applied. The low-cost and low-weight radar is ideal for autonomous security robots where real-time conditions are necessary.
