Distortion Analysis on Reflector Antenna Surface Using Non-Probabilistic Interval Method
This paper studies the analysis technique for complex antenna structures considering non-probabilistic uncertainty parameters. A method, which combines the interval matrix perturbation algorithm with the interval truncation algorithm, is proposed to analyze the distorted interval information for complex structures. Through the analysis of relative uncertainty of interval parameters, the criterion to determine the interval truncation factor is obtained. Two numerical examples, including a truss structure and a complex reflector antenna structure, show that the method is rational and feasible.
