Development of a Radar Pulse ModulatorNatter, Eckard Friedrich 01 January 1973 (has links) (PDF)
This report summarizes the design of a 25kW peak power pulse modulator for an airborne medium--range weather radar. It is the purpose of the modulator to collect and store energy over a certain time period and to form this energy into a short, high-power pulse. The modulator is required to drive a coaxial magnetron with a pulse of 5kV at 5A. System considerations make a pulse width of 3.5us and repetition rate of 99Hz necessary. The pulse is generated in a line-type pulse circuit which utilizes an SCR as a switching device. It is shown that a solid-state modulator can use a commercial grade SCR for the pulse generation. Although currents of 100A are switched, the instantaneous power dissipation in the SCR is reduced significantly through the use of a saturable delay reactor. A pulse transformer is used to achieve maximum power transfer from the modulator to the magnetron. The pulse transformer is insulated with semi-rigid epoxy. Corona generation is avoided by limited the voltage gradients in the insulation to 80V/mil.
