Abstract

PURPOSE:To generate a noise signal that has a center frequency and frequency spectrum with prescribed precision, by performing prescribed modulation and amplification of a received signal by use of a serrodyne traveling-wave amplifier tube. CONSTITUTION:To the helical electrode of serrodyne traveling-wave amplifier tube 13, a saw-tooth signal from saw-tooth oscillator 14 and a white noise, bandlimited by low-pass filter 16, from while-noise generator 15 are applied being superposed mutually by adder 17 and a received signal to be amplified by serrodyne travelingwave amplifier tube 13 in phase-modulated. Then, serrodyne traveling-wave amplifier 13 tube outputs a noise FM signal that has its center frequency shifted from the frequency of the received signal by the extent corresponding to the differential value of the saw-tooth signal and shows an electric spectrum whose electric power half-value width is distributed in a gauss shaped proportional to the electric power spectrum width of the while noise.
