摘要
现如今,图像信息频繁地被应用于军事、医学、民航等领域,尤其是在民航气象方面,气象雷达信号处理是雷达生产研究过程中的关键一环,也是一个难点.在实际中,通过雷达成像系统获得的雷达回波可能会造成一些关键信息的丢失,因此需要通过一些信号增强及复原技术来改善雷达信号的强度和准确度.本文介绍了数字滤波器的特点,如何通过MATLAB及其图像信号处理工具箱进行雷达数字图像处理,最终设计实现利用数字滤波器增强雷达图像信号.
At present,image information is frequently used in military,medical,civil aviation and other fields,especially in civil aviation meteorology,meteorological radar signal processing is a key part but also a difficult point of the radar production research process.In practice,the radar echoes obtained by the radar imaging system may cause the loss of some key information,so some signal enhancement and restoration techniques are needed to improve the strength and accuracy of the radar signal.This paper introduces the characteristics of digital filters,how to perform radar digital image processing through MATLAB and its image signal processing toolbox,and finally design and implement the use of digital filters to enhance radar image signals.
