我们提出了一种方法,通过使用断层数据采集模型作为统计推理的基础上,从聚光灯模式合成孔径雷达(SAR)返回的底层纹理结构的歧视。我们模拟的假设纹理统计自相似过程,并制定了假设检验框架中的SAR距离像域没有任何图像形成的问题。我们实现了一个接近最佳的,计算效率高的评价的似然测试通过将数据转换到多尺度域。
We propose a method for discrimination of underlying textural structures from spotlight-mode synthetic aperture radar (SAR) returns by using a tomographic data acquisition model as the basis for statistical reasoning. We model the hypothesized textures by statistically self-similar processes and formulate the problem in a hypothesis testing framework in the SAR range profile domain without any image formation. We achieve a near-optimal, computationally efficient evaluation of the likelihood test by transforming the data into the multiscale domain.
