Image formation method for spaceborne video SAR
2015 IEEE 5th Asia-Pacific Conference on Synthetic Aperture Radar (APSAR), 2015Spaceborne Video SAR imaging mode is a new imaging mode of SAR (Synthetic Aperture Radar), it is different from the traditional imaging mode. Operating in this mode, SAR provides continuous surveillance over a region of interest. Sequence images are processed afterwards and the information of the region is reappeared using video formed by sequence ...

Video Formation Method for UAV SAR Utilizing Tensor Recovery Algorithm
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Video synthetic aperture radar (SAR) have received more and more attention in recent years as it can provide continuous images of the observed area. However, the enormous data generated by the multi-frame images in video SAR brings big challenges to its transmission, storage and processing, especially for small unmanned aerial vehicle (UAV) platform ...

Moving Target Shadow Detection Based on Deep Learning in Video SAR
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Video SAR is a well-explored subject because of its high imaging frame rate and continuous monitoring of targets. Due to moving target shadow (MTS) is not defocused, it can reflect actual position of moving targets well, which makes it possible to detect the position of moving target by shadow.

Development of a video SAR for FMV through clouds
SPIE Proceedings, 2015The Defense Advanced Research Projects Agency (DARPA) is developing a Video Synthetic Aperture Radar (ViSAR) system designed to provide a targeting capability for the AC-130 gunship in conditions where the current electro-optic systems will not perform. By using radar, the gunship’s availability rises from 35% to 72%, as clouds currently obscure the EO/

Comparison of RD Algorithm and BP Algorithm in Video-SAR
2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2019Video synthetic aperture radar (Video-SAR) is a new imaging mode where a sequence of images are continuously formed and reproduced in video, which has unique advantages in moving target detection. In this paper, Range-Doppler (RD) and BackProjection (BP) algorithm are introduced for video-SAR image formation. The above two algorithms are applied to the

Moving target detection based on Circular Video SAR
2019 IEEE International Conference on Signal, Information and Data Processing (ICSIDP), 2019Video Synthetic Aperture Radar (Video-SAR) achieves radar video observation by continuously monitoring a certain area to form continuous image data of the target, and it plays an important role in civil and military fields. The SAR image of the moving target is defocused and deviates from its true position, but in its real position, a shadow area ...

Video SAR Moving Target Indication Using Deep Neural Network
IEEE Transactions on Geoscience and Remote Sensing, 2020Video synthetic aperture radar (SAR) has been found to be very valuable for detection and tracking of slow moving targets and for observing changes over short time periods. Shadows produced by target motion in sequential radar images can be used to detect targets themselves.

Applying stereo SAR to remove height-dependent layover effects from video SAR imagery
SPIE Proceedings, 2014This paper describes a correction technique using stereo SAR (Synthetic Aperture Radar) that improves the image quality of video SAR. The video SAR mode provides a persistent view of a scene centered at the Motion Compensation Point (MCP). The radar platform follows a circular flight path.
