Main Article Content
Abstract
This article provides a classification of non-linear radar used by the form of test signals and the mean exposure. The analysis of ways to improve the sensitivity of nonlinear radar to eavesdropping devices having small dimensions and having in its composition non-linear objects. The features of the use of complex signals in nonlinear radar. A method for increasing the sensitivity by use in conjunction with ultra-high frequency harmonic signal as the probe ultra-wideband pulse signal, whereby there is the effect of intermodulation due to which performed identification nonlinear objects among the plurality of reflectors, which do not apply to nonlinear objects. This effect is confirmed by using the software model «Matlab» and the results are shown in the form of spectrograms. The programming model is the foundation for the practical tests.
