The high resolution imaging of distributed targets in millimeter-wave radar system is studied in this paper. We use Gaussian Mrakov random field (GMRF) to represent the clustering property of the targets. Our novel method, called Clustering FOCUSS, incorporate an additional cluster constraint into the process of the focal underdetermined system solver (FOCUSS) algorithm. Simulation results indicate...
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...
