常见的基于人类视觉特性的图像增强算法由于是同时完成动态范围压缩和对比度增强,导致增强图像的整体对比度不高、边缘部分效果不佳.通过分析人类视觉系统的全局和局部自适应调节原理及人眼视网膜神经节细胞感受野的传输特性,提出一种仿生图像增强法.为适应人类视觉系统对光强的主观感觉特性,对图像作全局亮度对数变换 并利用人眼的主观亮度感觉与实际光强的对数呈局部线性关系的特性,采用视网膜神经元感受野三高斯 模型来调整亮度图像的局部对比度 最后利用线性变换恢复图像的彩色信息.实验结果表明,该算法的增强效果良好,特别是对于图像边界处,既能很好地增强边缘对比,又可有效地提升区域亮度对比和亮度梯度信息.

滑动聚束模式的RD成像。聚束模式SAR中,天线始终指向场景中心,合成孔径的长度比相同条件下的条带式SAR长。对于滑动聚束模式SAR系统,由于天线的指向变化与两者都不同,所以与条带模式相比,其合成孔径更长,而且测绘带区域比聚束模式更大 (The Sliding Spotlight model described in the article can geta better resolution than strip-map mode and better observed area than spotlight mode.by steering the antenna on a point further away the radar than the area beingilluminated which can be regarded as coming the underground. By doing this, thismode can get good combination between the resolution and observed area. )
