Towards Real Time Remote Sensing Laboratory: Image Enhancement via Hw/sw Co-design Paradigm
نویسندگان
چکیده
A novel remote sensing (RS) laboratory based on the hardware/software (HW/SW) co-design paradigm for the image enhancement/reconstruction problems pursuing the real time implementation is presented in this study. The application of the developed approach consider the typical single-look synthetic aperture radar (SAR) imaging systems operating in real-world RS scenarios with uncertainties attributed to random signal perturbations in inhomogeneous propagation medium (i.e., possible to imperfect system calibrations and carrier trajectory deviations). The proposed “real time remote sensing laboratory” (RTRSL) provides a HW-level platform for the evaluation of different collaborative RS imaging techniques using the Xilinx Virtex-4 XC4VSX35-10ff668 field programmable gate array (FPGA). Hardware implementation examples are reported to illustrate the usefulness of the developed RTRSL for system-level and algorithmic-level optimization of highresolution image enhancement tasks performed with the real-world RS imagery.

Hardware-software (HW-SW) co-design allows to meet systemlevel objectives by exploiting the synergy of hardware and software. Current tools and approaches for HW-SW co-design face difficulties coping with the increasing complexity of modern-day application due to, e.g., concurrency and energy constraints. Therefore, an automated modeling approach is needed which satisfies modularity, extensibil...
