Description

technical field

[0001] The invention relates to the field of electronic technology, in particular to a method for optimizing performance parameters of a phased array antenna pattern and electronic equipment. Background technique

[0002] The sidelobe level is a very important indicator of the phased array antenna. To a large extent, it determines the tactical indicators such as anti-jamming and anti-clutter of the antenna. The theoretical value of the antenna sidelobe level is determined by the illumination function of the antenna aperture. The weighting algorithms for achieving low sidelobe of phased array antennas include amplitude weighting, density weighting, and phase weighting, and their mixed weighting methods can also be used; in order to obtain the required antenna sidelobe level, the excitation current of each antenna element in the array The amplitude should be changed according to a certain irradiation function (such as Hamming distribution, Taylor distribution)...
