Estimation of the Target Detection Radar Noise Stability at the Ultrawideband Jamming Influence

Abstract

The field structure formation of an ultrawideband signal on the input of the target detection radar receiver device with working frequency 1 GHz is considered. The algorithms of the fields temporary structure definition based on the equations Кirghoff-Коthler with the subsequent estimation of the ultra−short impulse accidental jamming power characteristics necessary for specification of accepted signals processing algorithms are offered.

Analysis of temporal structure reflected from laying surface ultrawideband signals taking into account dispersion of reflection coefficient

“…In [1] the case of mirror antenna excitation by a diameter is considered 3 m and focal distance 1 m by the Gauss videoimpulse of single amplitude current by duration 1 nanosecond. Substantiated that for determination of the UWB signal spectral components magnetic field ( ) H ω by equation of Stratton-Chu it is expedient to take advantage of Кirhgoff-Коthler method and for the reflector surface S having eventual sizes to enter linear charges on a contour limiting a surface [2]:…”
