Effect of Noisy Input Signal and Electron Beam Velocity Nonuniform on Helix TWT Output Performance

Due to the complex electromagnetic environment in the helix TWT, the input signal is noisy, and the velocity magnitude and direction of electron beam from the electron gun to the slow wave structure are nonuniform. A simulation model for helix TWT output performance with different noisy input signal and velocity of electron beam is established and the results show that signal-to-noise ratio (SNR) ...
