“…На сегодняшний день довольно подробно изучены вопросы имитации отражений электромагнитных волн от реальных объектов. Известные результаты [1][2][3][4] находят применение в полунатурном моделировании сигнально-помеховой обстановки, что позволяет осуществлять настройку и проверку качества работы радиолокационных систем (РЛС) в лабораторных условиях. Это значительно удешевляет и ускоряет процесс тестирования системы в сравнении с натурными испытаниями.…”

“…Для моделирования эхосигналов от радиолокационных целей используют имитаторы. Наибольшее распространение получили матричные имитаторы (МИ) [1][2][3] в силу своих преимуществ: с их помощью на апертуре антенны исследуемой РЛС воспроизводится фронт электромагнитной волны, соответствующий отражениям от реальных объектов. При этом обеспечивается моделирование плавных перемещений цели с требуемой скоростью по заданной траектории.…”

This paper discusses the issues of constructing the configuration of a coherent matrix simulator for modeling echo signals of a two-position system. The condition is formulated in the form of a system of equations that the emitted signals are in-phase at both points of reception. A matrix satisfying this condition provides a simulation of a target in the same position for two spaced antennas. To ensure in-phase operation, it is proposed to use the possibilities of placing the radiators and controlling the initial phases of the signals. Relations are obtained for calculating the coordinates of the 2-point configuration and for calculating the phase addition value. Based on these relations, an algorithm for the synthesis of an extended one-dimensional matrix with the required angular size is developed. It is shown that the points of such a matrix can be located on one straight line. The obtained algorithm was used to synthesize a configuration of seven emitters for the given parameters of the two-position system. Using numerical experiments, the adequacy of the model was verified. Different positions of the point target were set, and a monopulse direction finder model was used to find its direction. The results of numerical experiments confirm the reliability of the theoretical results. They can be used in mathematical and simulation modeling of reflections from real radar targets for two-position systems.
