Abstract:
We present a new method for measuring spectra of microwave pulses. This method is based on iterative processing of detected signals after transmitting them through band-pass filters. In contrast to the well-known iterative methods [1-4], the proposed method includes the operator which is «gluing together» parts of the spectrum, corresponding to frequency bands of used filters. The method was tested in numerical simulations of various test signals and was implemented in spectrum measurements of the output radiation of an X-band relativistic backward wave oscillator (BWO).
