Description
Summary:Smart antennas are urgently needed in the expanding field of communications. Thus, the problem of beamforming is primarily considered. A modified windowed local polynomial approximation (LPA) including the acceleration term in Taylor series expansion is considered in this paper. The weighted least squares approach is applied for localizing and tracking rapidly accelerated moving sources. In this paper, LPA-beamformer performance expressions and the problem of the optimal window choice are studied.
