Abstract
The generalized ambiguity function in spatial coordinates and its approximate analytical representation are obtained for the multifrequency multiple-input multiple-output (MIMO) synthetic-aperture radar (SAR) system. The examples in which ambiguity-function cross sections in range and azimuth are calculated in the Earth remote sensing problem for the MIMO SAR system installed on a spacecraft and compared with those for the classical SAR system are presented. In the case of the MIMO SAR system, the physical meaning and the practical importance of an increase in azimuthal resolution are explained.
