A new approach for parallel implementation of synthetic aperture radar (SAR) imaging is presented. This approach is based on time domain correlation (TDC) which reconstructs radar imaging in spatial domain via Fourier transform using wave equation inversion theory. TDC algorithm can be modified for parallel implementation since it reconstructs images via matched filtering without any need for approximation...
Synthetic aperture radar has been used widely since it can provide high-resolution images. Many imaging methods have been proposed based on Fresnel approximation. These imaging methods are not applicable when synthetic aperture radar works at near field because the Fresnel approximation is completely wrong. Time domain correlation is a kind of digital reconstruction in spatial domain via Fourier transform...
To simulate synthetic aperture radar (SAR) raw data of extended scenes in the presence of arbitrary trajectory deviations, an efficient simulation scheme in hybrid domain is proposed. We firstly present a novel target-to-antenna distance model which takes the three-dimensional components of the trajectory deviations into consideration. Then a general and compact hybrid domain formulation of the SAR...
