Abstract

We consider the estimation of target directions in ultrawideband (UWB) multi-input-multi-output (MIMO) noise radar. We apply the tapped-delay-line (TDL) based beamforming technique to concentrate on receiving signals from a certain direction and to suppress interference from others. The conditional generalized likelihood ratio test (CGLRT) is applied for detecting target given the target impulse responses estimated by the CLEAN algorithm. Then, we propose the iterative CGLRT (ICGLRT) to determine their directions by implementing these two techniques iteratively.
