There is the problem of theoretical estimate of resolution in plane coordinates based on the derivation generalized correlation integrals (GCI) and generalized ambiguity functions (GAF) and their two-dimensional cross-section analysis when targets with small RCS are detected on short ranges and small height. The paper considers the theoretical derivation of GCI and GAF in plane coordinates for background radar in the approximation of the plane that allows to estimate the resolution in two-dimensional coordinates for various zones of detection volume. GCI and GAF cross-sections shape are obtained and studied, resolution estimate in horizontal plane zone is given. The proposed theoretical technique allows to give the theoretical estimate of target resolution in plane approximation.
