Summary
This Thesis discusses the use of super-resolution techniques applied for monostatic and bistatic radar imaging. ISAR and Bistatic ISAR theory is recalled and further considerations about linear and quadratic distortions, in terms of range/Doppler migration, due to the bistatic geometry are discussed. Analytical constraints for range and Doppler migration are defined and validated by means of simulated data. Then, super-resolution is theoretically treated by exploiting the monostatic and bistatic received signal models. Novel methods for super-resolution performance analysis and a novel super-resolution based approach for bistatic distortion mitigation are proposed. Super-resolution techniques are tested and compared on real monostatic and bistatic data. Such a real data consists of a SAR image of a vessel cropped by a SAR product provided by COSMO-SkyMed (monostatic) and an ISAR image of a small aircraft from the data collected during the NATO SET-196 trials from September 29th to October 3rd, 2014 (bistatic).
