The coherent-imaging principle of Synthetic Aperture Radar causes speckle niose, which is the major problem of SAR images. According to the characteristics of SAN image details and speckle distribution, this peper puts forward a speckle-reduction algorithm based on region division. This algorithm can protect edge-characteristics of SAR image, along with a very good speckle reduction effort. Eperimental result shows that this algorithm is better than other existing speckle reduction methods.

合成孔径雷达(SAR)因为相干成像原理所固有的相干斑噪声是影响其图像质量的主要原因。文中根据SAR图像的纹理特征和相干斑噪声的统计特征,提出了一种基于区域分集的相干斑抑制算法。本算法能够完全保留SAR图像边缘特征,同时对相干斑具有较好的抑制能力。实验结果表明,本算法处理效果优于目前常用的相干斑滤波算法

To evaluate the preformance of synthetic aperture radar (SAR) coherent speckle filtering algorithms, an evaluation system is proposed, including nine criteria: equivalent number of looks (or smoothing index), radiometric resolution, loss of the signal to clutter ratio, signal radiometric loss, bias, spatial resolution loss, edge keeping index, bias of the peak sidelobe rate and bias of integration sidelobe rate. This evaluation procedure can measure both the speckle suppression preformance and the loss of original information of the image. Test results of the real and simulated SAR images and typical speckle filtering algorithms show that these criteria are effective and in accordance with the visual assessment.

为了评价合成孔径雷达(syntheticapertureradar,SAR)图像相干斑滤波算法性能,提出了一个性能评价体系,其中包含9项指标:等效视数(或平滑指数)、辐射分辨率、信号杂波比损失、信号辐射度损失、均值偏差、空间分辨率损失、边缘保持指数、峰值旁瓣比偏差、积分旁瓣比偏差。该评价体系能同时衡量各滤波算法对相干斑的抑制程度以及对图像原始信息的保持程度。通过用真实图像和模拟SAR图像对典型相干斑滤波算法的检验,表明了评价指标的有效性。
