摘　　要：针对32通道毫米波焦平面成像中存在的像素偏移,提出了基于数据相关性进行像素校准的方法。给出32通道毫米波焦平面成像的原理,分析了像素偏移产生的原因。结合实际观测结果分析了图像中存在的像素偏移,重点阐述了利用数据相关性进行图像处理的步骤并给出了处理结果。实验结果表明,该方法能够很好的消除图像中的像素偏移,提高图像质量。Due to the presence of pixel deviation in 32-channel MMW focal plane imaging, a novel pixel calibration method based on data dependence is proposed. First, the principle of 32-channel MMW focal plane imaging is given in this paper, and the causes of the pixel deviation occurrence are further analyzed. Then, according to the observed results, this paper analyzes the existence of pixel deviation in image and gives the procedure of image processing based on data dependence in detail. Furthermore, the processing results are provided. Finally, the simulation results show that the new method proposed in this paper can eliminate pixel calibration and improve the quality of image effectively.
