Owing to the characteristics of long distance and strong penetration, a synthetic aperture radar (SAR) imaging system could provide ground information with high resolution under poor climate environment. Nevertheless, speckle is still common interference output that deteriorates content SAR images further affects recognition real objects. In this article, new suppression method proposed from pe...

In this letter, we aim to address a synthetic aperture radar (SAR) despeckling problem with the necessity of neither clean (speckle-free) SAR images nor independent speckled image pairs from same scene, and practical solution for (PSD) is proposed. First, an adversarial learning framework designed generate speckled-to-speckled (S2S) scene in situation where only single are available. Then, S2S ...

This paper presents two approaches for filter design based on stochastic distances for intensity speckle reduction. A window is defined around each pixel, overlapping samples are compared and only those which pass a goodness-of-fit test are used to compute the filtered value. The tests stem from stochastic divergences within the Information Theory framework. The technique is applied to intensit...
