On-Board Processing of Synthetic-Aperture Radar Backprojection Algorithm in FPGA

Synthetic aperture radar is a microwave technique to extracting image information of the target. Electromagnetic waves that are reflected from target acquired by aircraft or satellite receivers and sent ground station be processed applying computational demanding algorithms. Radar data streams an in order extract images since these processing algorithms computationally demanding. However, novel applications require real-time for analysis decisions so onboard necessary. Running on embedded systems with limited energy capacity challenge. This article proposes configurable hardware core execution backprojection algorithm high performance efficiency. The original restructured expose parallelism then optimized replacing floating-point fixed-point arithmetic. was integrated into system-on-chip architecture implemented field-programmable gate array. proposed solution runs over sizes $512\times 512$ notation="LaTeX">$1024\times 1024$ 0.14 s (0.41 J) 1.11 (3.24 J), respectively. notation="LaTeX">$2.6\times$ faster consumes notation="LaTeX">$13\times$ less than Jetson TX2 GPU. scalable and, therefore, tradeoff exists between utilization resources.
