Microwave beam
WebConsider a space-diversity microwave radio system. operating at an RF carrier frequency of 1.8 GHz. Each station has a 2.4-meter diameter parabolic. antenna that is fed by a 100m of air-filled coaxial. cable. The terrain is smooth and the area has a. humid climate. The distance between stations is 40. km. WebThe possibility is studied of attenuating the feedback wave in electron-beam-based Cherenkov microwave oscillators at the expense of its resonant interaction with the beam cyclotron wave under normal Doppler effect conditions. Oscillators operating in the regimes of the collective and single-particle stimulated Cherenkov effects are considered.
