An Improved FOCUSS Algorithm for Multi-Channel FMCW Radar Imaging of Distributed Targets

摘要：

In a Frequency-modulated continuous-wave (FMCW) radar system with multi-channel antenna array, the high resolution imaging of distributed targets is studied here. Motivated by the clustering property of the targets, we proposed a Clustering FOCUSS method by incorporating an additional clustered constraint into the solution of the FOCal Underdetermined System Solver (FOCUSS) algorithm. It is shown in the simulation for distributed targets scenario that the novel algorithm gets better performance in respect of imaging accuracy compared with methods of Capon beamforming,the L1-norm algorithm and the FOCUSS algorithm.
