Abstract

The invention discloses a phased array antenna directional pattern performance parameter optimization method and an electronic device. The method includes the following steps that: the performance parameter of the directional pattern of a phased array antenna is determined; an objective function corresponding to the performance parameter of the directional pattern of the phased array antenna is determined; the attenuation value of the T / R component of the phased array antenna is obtained, and the change value of the objective function corresponding to the attenuation value is obtained; and an optimal amplitude weighted iteration direction is determined based on the change value of the objective function. With the method provided by the invention adopted, the technical problem that the directional pattern performance parameter of an active phased array antenna in the prior art does not satisfy actual demands can be solved.

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)...
