Researchment of Mainlobe Anti-jamming Algorithms
Journal of Physics: Conference Series, 2020 Abstract Main lobe interferences usually cause the distortion and peak offset of main lobe and the heighten of side lobe level in adaptive beamformers. The block matrix algorithm utilized the direction vector which was determined by both the antenna arrays and the direction of interference to eliminate the main lobe interference.
