Signal Processing Algorithms for FMCW Moving Target Indicator Synthetic Aperture Radar
other
The combination of Frequency Modulated Continuous Wave (FMCW) technology and Synthetic Aperture Radar (SAR) leads to lightweight, cost-effective imaging sensors of high resolution. In FMCW SAR applications the conventional stopand- go approximation used in pulse radar algorithms cannot be considered valid anymore and so the motion within the
sweep needs to be taken into account. Analytical development of an FMCW SAR algorithm without the use of the stop-and-go approximation is presented in this paper and it is then validated by means of processing simulated and real data. Furthermore, the effects of a moving target as they appear in an FMCW SAR image are described and the results can be used to assist Moving Target Indicator (MTI) capabilities.
