Coherent Jitter in Impulse Radio Tomography

  • PHYSICS OF MAGNETIC PHENOMENA

Russian Physics Journal Aims and scope

A new method of increasing resolution of radio images due to nonlinear ultra-wideband data processing without any modification of the employed hardware is presented. The approach is applicable for stroboscopic filling of ultrashort impulses in which the error of triggering of a sensing impulse generator – a jitter – detected as noise in the gated data – is always presented. The nonlinear operation of selection of the coherent noise component in combination with the synthetic aperture radar (SAR) method provides a higher contrast of the radio image in comparison with operation of jitter smoothing. As a result, the physical effect of jitter occurrence that is typically negative yields a positive result. Examples of experimental data processing confirm this conclusion.
