Nanosecond pulse generators for magnetron operation

To operate with pulse durations of under 15 ns, most magnetrons require a special type of modulation signal. This paper describes the design and operation of practical short pulse modulator circuits providing magnetron outputs of as short as 7 ns. The resulting transmitters provide an economical approach to high resolution radar systems. The short pulse techniques have also been used to enhance the coherent operation of magnetrons which are being pumped with an RF reference signal.
