Space-based synthetic aperture radar systems are actively used for remote sensing of the Earth and have significant capabilities. Advances in microelectronics have made it possible to create and launch into orbit compact radars based on small satellites. Analysis of the capabilities of such radars is an actual problem. In this paper the issues of simulation and estimation of the antenna area, noise equivalent sigma zero, spatial and radiometric resolution of space-based synthetic aperture radars (SAR) operating on the basis of small spacecraft are considered. The necessary mathematical apparatus is given and the above values are calculated for the X-band SAR operating in strip mode at maximum resolution. The influence of the main technical parameters of space SAR on dimensions of antenna, on sensitivity, spatial and radiometric resolution is analyzed.
