Radio-frequency illumination sources based on ultrawideband microgenerators of chaotic oscillations

The task of wideband illumination of objects and surfaces by radiation from artificial noncoherent microwave sources with the aim of subsequent observation by radiometric equipment is considered. The main problem in solving this task consists in creating efficient microwave generators analogous to available sources of lighting in the visible spectral range. We propose to use generators of ultrawideband chaotic oscillations as sources of noncoherent microwave radiation. An experimental prototype of this source taking the form of a SiGe-crystal-based microgenerator of dynamic chaos is described.
