Abstract

Conventional SAR image formation includes the effects of only direct-scattering events. However, multipath events can be included in the measured phase history data. These multipath effects appear as "ghosts" in SAR images, thereby creating adverse image reconstructions. In order to separate the direct scatterers from the multipath scattering effects, an image reconstruction algorithm for multipath scattering (IRAMS) is applied. This method incorporates a wavelet-like inversion estimate of the multipath ghosts.

SAR图像重建中多径鬼影漂移反演估计

传统的SAR图像形成只包括直接散射事件的影响。然而，多路径事件可以包含在测量的相位历史数据中。这些多径效应在SAR图像中表现为“幽灵”，从而产生不利的图像重建。为了从多径散射效应中分离出直接散射体，提出了一种多径散射图像重建算法。该方法采用了一种类似小波的多径伪影反演方法。
