Abstract

The combination of Frequency Modulated Continuous Wave (FMCW) technology and Syntehetic Aperture Radar (SAR) leads to lightweight, cost-effective imaging sensors of high resolution. In rithms cannot be considered valid anymore, so the motion within the sweep needs to be taken into account. Analytical development of an FMCW SAR algorithm starting from the deramped signal and whithout using the stap-and-go approximation is presented in this paper; it is then validated processing simulated and real data. Furthermore, the effects of a moving target as tehy appear in an FMCW SAR image are described and the results can be used to assist Moving Target Indicator (MTI) capabilities.
