The article proposes and studies a mathematical model for the determination of the basic electrophysical properties of a dielectric object presented as a s

— The paper describes the operation of a classic step-recovery-diode-based pulse generator circuit using differential equations. The circuit has parasitic inductances and capacitors for both...

The possibility of applying the first principal component of the Karhunen–Loeve transform to localize reflections from a moving object on the time axis by sondaging with an ultra-wideband locator is s

This paper considers the possibility to employ the first principal component (Kahrunen-Loeve transform) to reveal the law of reflected signal phase modulation. The processing of modeled and real signals representing ultrawideband impulses reflected from a simple target and from a model imitating human breath was taken as an example. It is experimentally shown that, for small movements of the target, the first principal component’s movement trajectory follows the original law of reflected signal phase modulation with precision of not less than 20%.

This article describes a classic ground-penetrating radar, which includes a transmitter on two step-recovery diodes for the shock excitation of an ultra-wi
