Abstract: The paper proposes a description of the ambiguity function of the signal by objects ISAR imaging using direct integration methods and techniques of Fourier transformations. In some cases an exact and approximate estimation of ISAR image resolution and level of digital background are obtained, including single-frequency and circular imaging.

Key words: radar cross section, inverse synthetic aperture, radar images.
