The Influence of Phase Noises of High Frequency Generators on Stroboscopic Processing of Ultrawideband Signals

Presented results of investigation a linear mathematical model of a radio pulse stroboscopic system describe its behavior under phase instability conditions. There is shown an asymptotic estimate of efficiency sampling gate system depending on the phase noise magnitude and comparing the outcomes with experimental data. It can be seen that parasitic phase noise appears in the form of additional amplitude modulation of a useful signal. The passage of the phase noise of the reference oscillators through the path of the stroboscopic converter is considered.
