Relativistic Doppler frequency shift by a relativistic mirror of intense microwaves pulses appears as an efficient process for the generation of submillimeter waves at high energy level. The ability of electron beams to be used as a relativistic mirror for microwaves has been studied experimentally in two different situations : (a) in the case of a high impedance REB device (43Ω) and (b) with a low impedance REB machine (2Ω). The REB being an interesting and very powerful microwave generator is used as well as the microwave pulse source and as the relativistic mirror.
