The analytical relationships for defining the characteristics of multibeam arrays radiation on intermodulation frequencies have been obtained. The radiation specified has been shown to depend on the sum total of the amplitude-phase distribution and the corresponding direction patterns for each intermodulation frequency. The above direction patterns exhibit extended main lobes and reduced sidelobe ratios against basic frequencies radiation. Antenna beams deflection angles on each intermodulation frequency depend intricately on aspect angles and frequencies formed on the beam-s basic frequencies. The findings can be used for analyzing the performance of a space-frequency channeling communication system including a satellite communications system and for evaluating the electromagnetic compatibility of radioelectronic facilities. The article includes 5 figures and 3 reference items.
