Fast Factorized Back-Pro jection in an FPGA

<p>The Fast Factorized Back Pro jection (FFBP) algorithm is a computationally efficient </p><p>algorithm for image formation in a Very High Frequency Synthetic Aperture Radar (VHF </p><p>SAR) system. In this report an investigation of the feasibility of using an FPGA with a </p><p>hard CPU core to calculate the FFBP in real-time has been done. Two System on a Chip </p><p>designs for this task have been proposed for calculating the FFBP. A simplified version of </p><p>the FFBP has also been implemented in Matlab and used during this pro ject. The result </p><p>is that the computationally intensive parts, such as index generating and interpolation </p><p>calculations, should be implemented in the logic part of the FPGA and the CPU should </p><p>handle scheduling. This kind of modular system is easy to maintain and upgrade.</p>
