Influence of side radiation on one-reflector antenna parameters

The side lobes of an antenna´s directive pattern cause a decrease of its gain coefficient degradation of noise protection of radioelectronic systems equipped with this antenna, giving harmful effects of electromagnetic irradiation on the environment. Especially important is reduction of side lobes of the directive pattern of antennas of radiometric systems for remote sensing of atmosphere, hydrosphere and Earth surface. In this connection the investigation to find opportunities to reduce the side irradiation of one of the main types of sharply-directed mm-band antennas-reflector antennas-is topical and urgent for many practical applications in scientific instrument-making and technique. The subjects of investigation in this work are levels and law of reduction of side lobes of directive pattern of parabolic reflector antenna
