Use of ultra-wideband signals in nonlinear radar

Abstract

The analysis is given of the ways to improve the sensitivity of nonlinear radar to eavesdropping devices having small dimensions and having in its composition nonlinear objects. We investigated the method to increase the sensitivity by using, as the probe signal ultra-wideband pulses together with the harmonic signal of microwave frequency, which could result in intermodulation effect, through which run the identification nonlinear objects among the plurality of reflectors, which do not apply to non-linear objects.
