摘要：a frequency control system is controlling the high frequency of a magnetron(22) mechanically coaxial tuned in a wide range of environmental conditions in syntonisantoriginally the magnetron (22) as a function of tuning data of resident and r response to areceived signal to control the frequency.by directly measuring the frequency of theoutput of the magnetron, by comparing the control signal with the frequency of theactual frequency of each of the pulses in a series of output pulses are sampled byaltering a function of dynamic adjustment based on calibration any differences found inthe comparison.in resyntonisant the magnetron (22) according to the modified calibrationfunction, and repeating the process to maintain the output frequency of the magnetronin accordance with the frequency control signals. the coefficients of the calibrationfunction converge to an optimum set of values within a range of a few impulses.afrequency offset can be effectively corrected with the measurement of the pulse. otherfrequency control characteristics, such as slope and nonlinearity, can be corrected withthe measurement of pulses at different frequencies.
