Abstract. In this paper methodology of conceptual design of airborne radar with synthetic aperture antenna (SAR) in the framework of mathematical technology paradigm is under investigation, moreover main attention is paid to physical but not phenomenological models. Performance criterions of design for SAR as a whole system and for its subsystems have been introduced. Approximation of specific effective dispersion section matrix on remote sensing data by means of  two-dimensional atomic interpolants,  two-dimensional atomic Kravchenko wavelets and  two-dimensional generalized Kotelnikov theorem with vector-parametric atomic functions is considered. On the basis of  the theory of growing interfaces and the classical problem on diffraction of plane electromagnetic wave by wedge exactly solved models of electrodynamic properties of surfaces in cold regions of the Earth are constructed.

Keywords: conceptual design, system analysis, mathematical technology, performance criterion, the physical theory of diffraction, SAR, radar image, atomic functions, method of characteristics, specific effective dispersion section.
