摘要
针对低信噪比雷达图像的特点,在Radon变换的基础上利用机场目标和背景的雷达成像知识对Radon变换的结果进行后处理,以便可靠地提取雷达图像中的机场目标。为了对机场进行定位,给出了一种确定线特征端点的简单有效的方法。同时给出了一种距离变换准则来衡量提取到的线特征和真实线特征的相似度。实验表明,该方法能更可靠地提取雷达图像中的机场目标。
In order to extract airports from the lower SNR radar images reliably, the knowledge about radar imaging is used to post procession of the results of Radon transform. A simple and efficient way is given to find the end points of line features and a kind of distance transform rule is given to weight the similarity of the extracted line features and the real line features. The experimental result shows that this method is effective on extracting airports from radar images.
