Dual Carrier Probing for Spaceborne SAR Imaging
Spaceborne imaging of the Earth’s surface by synthetic aperture radar (SAR) may be adversely affected by the ionosphere that causes distortions of the signals emitted and received by the radar antenna. In our previous publication on the subject [SIAM J. Imaging Sci., 2 (2009) pp. 140–182], we have analyzed those distortions for the inhomogeneous ionosphere described by the cold plasma model. Ba...
متن کاملSpaceborne SAR Imaging Algorithm for Coherence Optimized
This paper proposes SAR imaging algorithm with largest coherence based on the existing SAR imaging algorithm. The basic idea of SAR imaging algorithm in imaging processing is that output signal can have maximum signal-to-noise ratio (SNR) by using the optimal imaging parameters. Traditional imaging algorithm can acquire the best focusing effect, but would bring the decoherence phenomenon in sub...

متن کاملA real time SAR processor implementation with FPGA
Great numerical complexity is a characteristic of synthetic aperture radar (SAR) image synthesis algorithms that poses a particularly serious problem for realtime application. Advances in the operating speed and density of the field programmable gate arrays (FPGA) have allowed many high-end signal processing applications to be solved in commercially available hardware. A realtime SAR image proc...
