Abstract

Questions of identification of the mortgage devices (MD) on tunnel diodes which are in a waiting mode or work for record in memory of a chip, by means of nonlinear radars are considered. Conditions of change of a ratio on opposite between levels of spectral components of a scattered signal when sounding by the nonlinear radar of the considered class of mortgage devices are investigated. Inverse change of this ratio significantly worsens reliability of an identification sign of nonlinear scatterers based on the ratio of levels of multiple harmonics of a response signal. It is shown that a N-like form of the volt-ampere characteristic (VAC) of the nonlinear devices which are a part of the scatterer, amplitude of the induced signal and shift of a working point to VAC are the reasons of inversion in the ratio of levels of harmonics of the reradiated signal. Influence of a VAC form of the tunnel diode on reliability of identification of the MD introduction of the approximating dimensionless coefficients in the way and is analyzed. It is offered to use new variables not only for the characteristic of a curve form, but also for an assessment of reliability of MD identification based on the ratio of harmonics levels of the unmasking signal in general. The analysis of an identification sign of scatterers based on the ratio of levels of multiple harmonicas by means of parameters also allows to minimize influence of unreliable operating modes of nonlinear radars on efficiency of carrying out search actions.
