Inverse Airborne Optical Sectioning
We present Inverse Airborne Optical Sectioning (IAOS), an optical analogy to Inverse Synthetic Aperture Radar (ISAR). Moving targets, such as walking people, that are heavily occluded by vegetation can be made visible and tracked with a stationary ...

Inverse Synthetic Aperture Radar Sparse Imaging Exploiting the Group Dictionary Learning
Sparse imaging relies on sparse representations of the target scenes to be imaged. Predefined dictionaries have long been used to transform radar target scenes into sparse domains, but the performance is limited by the artificially designed or existing ...

Multipath Smearing Suppression for Synthetic Aperture Radar Images of Harbor Scenes
Due to the periodic and non-periodic variations in the sea surface, smearing is caused by the multiple paths between the sea surface and man-made objects in synthetic aperture radar images of harbor areas. This smearing can cover real targets and lead to

Inverse Synthetic Aperture Radar Imaging Using an Attention Generative Adversarial Network
The traditional inverse synthetic aperture radar (ISAR) imaging uses matched filtering and pulse accumulation methods. When improving the resolution and real-time performance, there are some problems, such as the high sampling rate and large amount of ...
