Derivative Constrained Robust Lcmv Beamforming Algorithm

By Rui Li, Xin Zhao, and Xiao-Wei Shi
Progress In Electromagnetics Research C, Vol. 4, 43-52, 2008

Abstract

A class of linear derivative constraints, which provides robustness to the conventional narrowband uniform linear array configuration so as to handle broadband and moving jammer sources problem is presented. The robust modification of linear constrained minimum variance (LCMV) algorithm is given to broaden the null widths in the jammer directions. Numerical results show that the proposed algorithm has a better performance in broadband and moving jammer scenarios in terms of maintaining beamwidth broadening and capability of rejecting interferences.
