Abstract
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.
Keywords
