Non-Uniformity Correction Algorithm Research Based on One FPGA Processor

Abstract:

The two-point non-uniformity correction based on Least mean square (LMS) algorithm which was proposed by Suxia Xing need one FPGA processor, one DSP processor and four SRAM chips. This will increase the cost and volume of the whole infrared system. In the LMS algorithm, this paper improves the estimation of the ideal signal, so that it can reduce the influence of blind elements and improve the effect of non-uniformity correction. Besides, this paper realizes the two-point non-uniformity correction based on LMS algorithm with only one FPGA processor and two SRAM chips in the final, this will reduce the volume, weight, cost of the whole infrared system. Comparing with the two-point non-uniformity correction based on one FPGA processor, this paper did not need blackbody with uniform radiation in system. Above all, the method of this paper is useful and practical.
