TL;DR: In this article, a large-scale antenna track irregularity modeling method based on Fourier series and a fractal function is proposed, which comprises the following steps: measuring the surface irregularity of a track, and setting a Fourier Series expansion order initial value and a Fractal Function fitting length initial value in a model; fitting a large scale profile by adopting the Fourier-series, and solving by adopting a least square method; verifying the accuracy of the FIFO series, and determining a FFFO expansion order; establishing a fractAL function-based optimization model

TL;DR: In this article, a regulating method for distributed MEMS phase shifter working voltage based on phase shift magnitude electromechanical coupling was proposed, and the regulating method comprises the steps that structural parameters, material properties, and electromagnetic working parameters of distributed MRS phase shifters are determined; a working voltage standard value V and a phase-shift magnitude standard value deltaphi are determined, and equivalent circuit parameters and working voltage regulating amount are calculated.

TL;DR: In this article, a method for calculating the beam pointing error of a large antenna with an arbitrary pose based on track unevenness is proposed, which can accurately reflect the antenna track surface.
