ALGORITHM AND PROGRAM COMPLEX FOR ANALYSIS OF THE CHARACTERISTICS OF PLASMA RELATIVISTIC ULTRAHIGH FREQUENCY GENERATOR OUTPUT RADIATION
AbstractThe article proposes a method for processing experimental results obtained from plasma relativistic ultrahigh frequency (UHF) generator (PRG).
For gathering information about a PRG output radiation spectrum with high time and frequency resolution, the authors use wavelet transformation and digital filtration of signal, presenting output radiation of PRG. The program has been written in the MATLAB language in the MATLAB 7.0 environment. The sampling interval of the PRG output signal is equal to 50 ps. The plasma relativistic UHF generator, built on Sinus 550-80 accelerator, has some unique properties: PRG has a single impulse mode and a multiple impulses mode (up to 50 pulses per second); PRG can generate pulses with durations of 80 ns and frequency band lying in 2 to 25 GHz area of spectrum; PRG can generate an UHF radiation in single frequency and multifrequency modes. By alteration of starting parameters such as plasma density, one can switch between different PRG work modes and, by that, one can regulate some of radiation characteristics such as carrier frequency or bandwidth or other. To make control of PRG output radiation possible, a complex of program and signal-gathering devices were created. The relation between different initial parameters of experiment and PRG output radiation spectral characteristics needs to be investigated.
