Abstract :
A technological development in the design of electronic-frequency-tuning pulsed magnetron has the potential to dramatically increase the information in the high-power X-band radar-detecting signal by the use of frequency modulation. This achievement is necessary to meet the increasing world demand of distinct remote sensing picture use of the radar. The developed and improved electronic-frequency-tuning magnetrons utilize new techniques to tune the oscillation frequency by applying tuning voltage. The high-tuning-frequency response rate allows for frequency modulation within the pulse duration of radar´s transmitting signal. This paper provides a detailed explanation of the design methodology and the measured data using this technology with actual X-band 4- and 12-kW electronic-frequency-tuning magnetrons.
