Research on the MODE-TOEP Beamforming Algorithm
模式空间矩阵重构波束形成算法研究

The MODE-TOEP beamforming algorithm is proposed to suppress the coherent interference on a Uniform Circular Array (UCA). Firstly, the mode space transformation is used to transform the UCA into a Virtual ULA (VULA). On this base, a Toeplitz matrix can be reconstructed. Then EigenSpace-Based (ESB) beamforming is applied to suppress the coherent interference successfully. MODE-TOEP beamforming algorithm has less computational burden due to non-spatial smoothing but has a better performance of the interference suppression compared with conventional MODE-SS beamforming algorithm. Simulation results show the validity and merit of the MODE-TOEP beamforming algorithm.
