Synthetic Aperture Radar(SAR)is an important tool for geosciences,remote sensing, surveillance,& reconnaissance now a day. In this work,a definition of UWB SAR image quality measurements is presented and the measurements for the UWB SAR images are performed. The most important SAR image quality assessments are spatial resolution, differential resolution, ISLR and PSLR. It is seen that elliptic areas are more suitable for delimitation of mainlobe and sidelobe areas of a UWB SAR image than rectangular areas for measurements of ISLR and PSLR. For this purpose a newly defined Impulse Response Func...
Synthetic Aperture Radar(SAR)is an important tool for geosciences,remote sensing, surveillance,& reconnaissance now a day. In this work,a definition of UWB SAR image quality measurements is presented and the measurements for the UWB SAR images are performed. The most important SAR image quality assessments are spatial resolution, differential resolution, ISLR and PSLR. It is seen that elliptic areas are more suitable for delimitation of mainlobe and sidelobe areas of a UWB SAR image than rectangular areas for measurements of ISLR and PSLR. For this purpose a newly defined Impulse Response Function (IRF-SAR) is used instead of the widely used sinc function. In this book, the simulated CARABAS-II data is employed and the simulations are performed by Matlab. Global back projection (GBP), a time domain algorithm is used due to its time-domain characteristics such as extreme range migration handling and manageable motion compensation. But its main limitation is computational cost. This book uses a simple and causal writing style to presents the SAR image quality measurements pleasantly and nicely so that readers can enjoy it easily.
