|1A bipolar voltage pulse length by the amplitude level of 0.1. |
2Repetition rate is controlled in the limits of 1-100 Hz.
3A pattern width by the half-level of the peak power in the horizontal and vertical planes.
The novelty of the sources proposed is that they use conceptually new combined radiators and antenna arrays based on these radiators and excited by high-power bipolar voltage pulses. The efficiency of the conversion of electric pulses into electromagnetic radiation by energy and peak power reaches 90%.
No analog has come to the authors' notice.
Full-scale testing results
Full-scale testing of the systems has shown that they are capable to generate with high reliability and reproducibility ultrawideband radiation pulses with the parameters listed in Table.
Suggestions for collaboration
It is suggested to sell the ultrawideband radiation sources on the partnership basis and to develop new versions of the sources in accordance with customer's assignments.
