Abstract. A simplified method is proposed for estimating the parameters of the amplitude radiation pattern of a large-aperture two-mirror antenna system based on the field distribution over the aperture of the horn irradiator and the geometric characteristics of the antenna. The simula­tion results are compared with experimental data.

Keywords: two-reflector antenna, radiation pattern, far zone, amplitude distribution of the field.
