A High-Power Source of Ultrawideband Radiation with Reflector Antenna

Characteristics of a source of linearly-polarized ultrawideband (UWB) pulse radiation based on the irradiation of a offset-parabolic reflector by a compact UWB combined antenna was investigated in the paper. The feed antenna was excited by a bipolar voltage pulse of the amplitude up 100 kV and duration of 1 ns at the pulse repetition rate of 200 Hz, The developed source is designed to use in radar with high spatial resolution and to test radio-electronic systems.
