Abstract: In order to achieve greater performance of hyper beamforming algorithm, this paper proposes an Improved Hyper Beam Forming (Im-HBF) method based on the higher order operation of whole array instead of half array. Simulation results show that the Im-HBF method can get greater reduction of beam width and grating lobe and better detection performance. The Im-HBF method can be satisfied with the index of n in generalize, although the index of n>2 also could get better performance than Conventional Beam forming (CBF).
