Abstract

The invention discloses a method for analyzing the gain and phase center of a multi-beam phased-array antenna, and belongs to the technical field of multi-beam phased-array antenna analysis methods. The method comprises the steps of parameter input, phase difference calculation, calculation of the number of antennas mainly participating in radiation, array field intensity accumulation, gain and phase center calculation and the like. Multi-beam array synthesis can be performed on any array, a gain directional diagram and a phase center distribution diagram are formed, the method is used for performing phase center distribution simulation on an array antenna in a specific form, and meanwhile, through specific parameter setting, the influence of random and engineering errors such as array element spacing, array form, random array element failure and the like on an array antenna gain directional diagram and a phase center is realized.

Description

technical field [0001] The invention belongs to the technical field of multi-beam phased array antenna analysis, and in particular relates to an analysis method for multi-beam phased array antenna gain and phase center. Background technique [0002] The multi-beam phased array antenna can adjust the beam pointing and beam shape, and when it moves within the field of view, the coverage characteristics of a specific area are basically unchanged. Therefore, it is widely used in the fields of satellite communication, measurement and control, and military tactical communication. [0003] The gain and phase center of a multi-beam phased array antenna are affected by the number of synthesized beams, the array pattern and directivity pattern of the element antenna, and can usually only be obtained through electromagnetic simulation software simulation. However, limited by the computer's memory and processor capabilities, it takes a long time to obtain results through electromagneti...
