The antenna characteristics of non-sinusoidal waves (NSW) are described in receive mode. With the use of three types of reciprocity theorem for pulsed fields, it is shown that the spatial and temporal antennas characteristics in the transmit and receive modes are different because of different current distribution on the antenna to transmit and receive modes. Two approaches are proposed: it is necessary to find the spatial and temporal distribution of the current in the antenna in receive mode for the determination of antenna NCW, don't take the separation of antenna characteristics in receive and transmit modes, and use a two-way response characteristic in the form of mutual convolution relation.
В статье рассматриваются характеристики антенн несинусоидальных волн (НСВ) в режиме приема. С использованием трех видов теоремы взаимности для импульсных полей показано, что пространственно-временные характеристики антенн в режимах передачи и приема разные, поскольку отличаются распределения токов на антенне в режимах передачи и приема. Предложены два подхода: для определения характеристик антенн НСВ в режиме приема необходимо найти пространственно-временное распределение тока на антенне в режиме приема; не проводить разделения характеристик антенн в режимах приема и передачи, а использовать одну приемно-передающую характеристику в виде соотношения их взаимной свертки.
