SAR imaging algorithm for the burden surface in BF based on cok algorithm

摘要

According to the principle of two-dimensional SAR imaging, a new algorithm is proposed for the burden surface of blast furnace(BF). The cable phase correction and background suppression technology reduces the influence of noise efficiently in the test environment. As the proposing of the threshold denoising method of SAR BF imaging, the imaging resolution improves by 22.6% at the azimuth direction and the peak SNR reaches 48.13. The imaging of the shape of the coke and iron ore and simulated stock line for raw materials has been realized, of which simulation and experiment results verify the effectiveness and feasibility of the new algorithm in the laboratory.
