Abstract
A magnetron transmitter having a two-stage modulator, one stage generating long, slowly rising, low power pulse, and the other generating a short, high power pulse, whereby high resolution is obtainable without the use of pulse compression techniques.
Claims6
A short pulse magnetron transmitter, comprising:
- a control signal input;
- a long pulse generator coupled to said input for generating a long, low power level pulse in response to said control signal;
- a short pulse generator coupled to said input for generating a short, high power level pulse in response to said control signal, including means for delaying the generation of said short, high power level pulse;
- a magnetron coupled to said long pulse generator and said short pulse generator such that said magnetron is placed in oscillation by said long, low power level pulse and is driven to high power by said short, high power level pulse.
1 more element
The transmitter of claim 2 wherein said long pulse generator includes a first thyratron switch and said short pulse generator includes a second thyratron switch.
