Integrated antenna feed system quality degree measuring method

Abstract

The invention discloses an integrated antenna feed system quality degree measuring method, and aims at providing a correct, rapid and economic method which satisfies the product evaluation demands. The method is realized through the following technical scheme: in allusion to an integrated antenna feed system product, dividing the integrated antenna feed system product into function layers or forming modules according to the component, respectively listing technical indexes which represent the function and performance characteristics, and establishing an integrated antenna feed system quality evaluation system model; in allusion to each index, comparing the expected value of the index with the measured value formed by an integration process, and converting the difference between the expected value of the index and the measured value into single-index quality degrees of the function layers or the modules according to an index normalization and data mapping transformation method; and solving the weight value of each index and the weight vectors of the function layers and the modules by a fuzzy consistency judging matrix according to an index weight calculation method, calculating the quality degrees of the function layers and the modules according to a weight sum manner, and evaluating the quality of the antenna feed system according to a calculation result which indicates that the quality degree of the system is equal to the weight sums of quality degrees of the function layers.

Description

Technical field [0001] The invention relates to a quality evaluation method of a complex phased array system antenna feeder equipment. Background technique [0002] There are two main types of measurement methods for product quality: measurement methods and counting methods. 1. The method of measurement. When the quality characteristics of a unit product change continuously, the measurement method can be used. In other words, all continuous random variables can be measured by measuring the quality characteristics of a unit product. For example, the tensile strength of the steel wire rope and the life of the picture tube can all be measured. Suitable for quality control such as length, weight, time, strength, composition and certain electrical parameters. 2. The counting method. Any discrete random variable can be counted. The counting method is divided into point counting and piece counting. When the quality characteristics of a unit product are measured by the discrete sc...
