This paper proposes the optimization method for geometry of the double curvature reflector of mirror antenna. The forming of the cosecant pattern for given frequency range, which is determined by irraditor properties, is considered. Mathematical model of the mirror antenna is based on the methods of geometrical optics. The usage of computational methods of high accuracy allows to accelerate the proposed method of successive approximation.
Предложен метод оптимизации геометрии рефлектора зеркальной антенны двойной кривизны. Рассматривается формирование косекансной диаграммы направленности в полосе частот, определяемой свойствами облучателя. Математическая модель зеркальной антенны основана на использовании методов геометрической оптики. Использование вычислительных методов повышенной точности позволяет существенно ускорить предложенный метод последовательных приближений.
