Improvements in space radiation-tolerant FPGA implementation of land surface temperature-split window algorithm

The trend in satellite remote sensing assignments has continuously been concerning using hardware devices with more flexibility, smaller size, and higher computational power. Therefore, field programmable gate arrays (FPGA) technology is often used by the developers of scientific community equipment for carrying out different algorithms. This article explains implementation land surface temperature split window (LST-SW) algorithm based on FPGA. To get a high-speed process real-time application, VHSIC description language (VHDL) was employed to design LST-SW algorithm. paper presents benefits Virtex-4QV radiation tolerant series experimental results revealed that suggested Virtex4QV achieved throughput 435.392 Mbps, faster processing time value 2.95 ms. Furthermore, comparison between proposed existing work demonstrated better performance terms area utilization; 1.17% reduction number Slice 1.06% LUTs. Moreover, significant advantage utilization would be none use block RAMs comparing three blocks RAMs. Finally, show improvements rates 2.28% frequency, 3.66 x throughput, 1.19% time.
