摘要 在现代船舶中,航海雷达广泛应用于航海导航、目标物检测跟踪及安全运行等领域,所以在船舶中配备实时高效的雷达数据及图像处理系统成为利用航海雷达的关键。同时,小波变换由于其具有高分辨率的图像处理功能而在图像处理领域得到了较为深入的研究应用。本文研究航海雷达图像信息中混入噪声及杂波的分布特性,提出一种基于小波变换的雷达图像数据杂波抑制、去除噪声的方法,最后给出仿真结果并进行分析。 In the modern ship, navigation radar have become the indispensable equipment, it use for maritime navigation and object detection. So the efficient real-time radar data and image processing system become the important equipment on modern ship. This paper first analyzes the characteristics of ocean ripple loud noise, last proposed a radar image processing technology based on wavelet transform.
