Power spectrum of the millimeter wave noise oscillator with the frequency modulation

At present time radio electronic systems designed on principles of the use of noise signals are under intensive investigation. The methods of signal processing in such systems can differ depending on their designation. However, in general the primary sources of noise signals (sources of noise oscillations) with the given characteristics are necessary for their operation. In this work, by means of numerical modeling, the capability of obtaining of a narrow-band noise signal in the MM-wave range using frequency modulation (FM) by a low frequency noise signal is investigated. On the basis of the obtained results some practical recommendations on the realization of FM generators to obtain signals with the required spectral characteristics can be given.
