Application of Kravchenko Windows in Problems of Formation of the Radar Subsurface Layers Images by the Onboard Radar of Subsurface Sensing

Usage of Kravchenko windows as envelopes of radar signals and form of a field pattern in the synthesized aperture allows to receive ambiguity functions of a system IPQ with optimum parameters of efficiency and to improve the quality of allocation of subsurface layers. The main attention is given to the analysis of ambiguity functions (AmF), radar signals and field pattern in the antenna with the synthesized aperture, fluidized classical windows and new Kravchenko windows. As a result of a simulation modeling the individual parameters of efficiency and integral parameter of efficiency (IPE) are obtained. Which analysis allows to reveal optimum weight functions used in radar station with the synthesized aperture (RSA) and modulation of radar signals.
