The paper proposes an antenna reflector’s quality assurance method for space communication systems. It requires meeting a specified condition for the method’s application, which includes matching the tolerance by the standard deviation of reflector surface geometry and reflection coefficient values. After meeting the condition control of other reflector parameters from listed quality indices nomenclature can be permitted. The nomenclature is based on require-ments of standard and technical product documentation and including device working ability’s base characteristics. The method consists of complex quality index calculation. Complex quality index can be calculated by using differ-ential method, comprising in a comparison between real and standard (ideal) values of reflector parameters from the listed nomenclature. The actual data for the calculation are collected during quality control and testing. The summary formula of the complex quality index is introduced for the purposes of determining the product quality level value for impersonal technological process evaluation. For comparative assessment of complex quality index within a single production lot, this paper proposes rating scale categories based on ABC analysis and Pareto principles and includes three categories. This index is a quantitative estimate of reflector quality and can be used for further analysis purposes and managing of production manufacture’s technological process. In addition to the method implementation example of the calculation algorithm for space receiver system reflector from polymer composite material of Ku-frequency is demonstrated. The developed method application is a crucial pre-condition for quality assessment level of reflector, technology improvement and for defective products prevention.
Keywords: control, quality management, reflector, assessment method.
