The article was published in issue no. № 3, 2024 [ pp. 310-317 ]Abstract:This paper is intended to introduce domestic engineers and researchers to the feature selective validation (FSV) method, which is widely used by foreign specialists in radio-engineering and electronics for quantitative evaluation of the agreement between two datasets (for example, when comparing the results of simulation and experiment). For this purpose, the paper presents a new open source software tool based on the FSV method. It also gives theoretical information about the method and shows examples of its use, describes a FSV data comparison procedure in detail. The paper notes the peculiarities of data partitioning into subranges, the basics of calculating measures indicating the difference between sets, and the interpretation of calculated measures when constructing evaluation histograms. The developed block diagram visually describes the algorithm of the FSV method and the specifics of its software implementation. A software tool based on the FSV method was developed in C++ using this block diagram. The paper provides information about the development tools, software architecture, graphical user interface, and functionalities. The final part of the paper presents examples of applying the FSV method in the form of global difference measure histograms obtained by comparing four data sets describing complex and non-linear frequency dependencies: voltage in a multi-conductor transmission line, shielding effectiveness of a metal enclosure, modulus of the transmission coefficient for a wire structure, electric field strength outside an apertured cavity. The results showed that the developed software tool and the FSV method allow obtaining a reliable quantitative assessment of the agreement between two data sets, even when their qualitative visual comparison is difficult.
Аннотация:Данная работа посвящена методу валидации выделением особенностей (FSV), широко используемому зарубежными специалистами в области радиотехники и электроники при количественной оценке совпадения двух наборов данных (например, при сопоставлении результатов компьютерного моделирования и эксперимента). Для этого создано новое свободно распространяемое программное средство на основе метода FSV, представлены теоретические сведения о методе, а также примеры его использования. Так, приведено описание процедуры сопоставления данных методом FSV. Отмечены особенности разбиения данных на поддиапазоны, основы получения мер разности между наборами и интерпретации рассчитанных мер при построении оценочных гистограмм. Разработана блок-схема, наглядно описывающая алгоритм работы метода FSV и специфику его программной реализации. Используя эту блок-схему, на языке C++ разработано программное средство на основе метода FSV. Приведены сведения об инструментах разработки программного средства, его программной архитектуре, графическом интерфейсе пользователя, а также о функциональных возможностях. Даны примеры использования метода FSV в виде гистограмм глобальной меры разности, полученных при сопоставлении четырех наборов данных, описывающих сложные и нелинейные частотные зависимости: напряжения в многосвязной линии передачи, эффективности экранирования металлического корпуса, модуля коэффициента передачи проводной структуры, напряженности электрического поля снаружи резонатора со щелью. В результате показано, что разработанное программное средство и метод FSV позволяют получить достоверную количественную оценку совпадения двух наборов данных даже тогда, когда их качественное визуальное сопоставление затруднительно.
