Beam-Space Domain Angle Estimation Algorithm in VHF MIMO Radar
摘要
Abstract
A low angle estimation method based on beam-space domain in very high frequency (VHF) multiple-input multiple-output (MWO) radar is proposed. The multipath signal model for MEMO radar is constructed with both transmitted multipath and received multipath signals being considered.Firstly,some receiving beams are formed. Secondly,a matched filterbank is used to extract the transmitted orthogonal waveform components.Thirdly,some transmitting beams are formed at the receiving side.Thus, the array data is mapped from element space into beam space. Finally, a modified generalized multiple signal classification (MUSIC) algorithm is developed for angle estimation after beam-space pre-processing.Compared with the element-space processing, the proposed algorithm has nearly the same estimation precision and owns lower computational burden. Theoretical analysis and computer simulation results demonstrate the merits of the new algorithm.关键词
