Investigation of the sparse antenna array properties in the radio-imaging systems

The new spheres of remote sensing system applications make demands for improving of the mass-size and economic characteristics of airborne portable radio-imaging systems, i.e. large aperture systems. First of all these demands are concerned with antenna structures. Application of sparse antenna structures offers the possibility of decreasing the number of antenna feeder elements which improves the above-mentioned performances of these systems. This paper is devoted to the study of the properties of sparse antenna arrays and their application in radio-imaging systems.
