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.
