Abstract
A high-power source of ultrawideband radiation of subnanosecond duration based on a hybrid antenna with an offset reflector has been developed. At the focus of the reflector, there is an array of 2 × 2 combined antennas excited by a four-channel bipolar voltage pulse former with an amplitude of 60 kV and a duration of 0.5 ns at a repetition frequency of up to 100 Hz. Radiation modes with discrete scanning of the wave beam, as well as with linear, orthogonal, and elliptical polarizations, were implemented. Radiation pulses with a field strength of 40–120 kV/m at a distance of 4.5 m were obtained.
