Robust shadow tracking for video sar
Webconventional SAR imaging is far lower than the need for target tracking. this problem, a new SAR system, Video-SAR or ViSAR is proposed by Well in 2003 [1], which can obtain image sequence of target area and reproduce area information in a movie-like form. ViSAR meet the more needs for target tracking and monitoring than conventional SAR.

Webadshelp[at]cfa.harvard.edu The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A WebThe moving target is always defocused and shifted out of the scene in image sequences in video synthetic aperture radar (video SAR), resulting in a shadow in the real position. The tracking-by-detection framework is often adopted in solving tracking problems. However, when multiple targets are tracked simultaneously, the association between targets and …
WebJun 7, 2024 · Abstract. Shadow detection and tracking (SDT) is the effective method to locate moving targets, which always be shifted or smeared outside the scene, in different images sequence by Synthetic Aperture Radar (SAR). In this process, the detection of shadow is obtained on the first frame image, and the Kernelized Correlation Filter is used … WebApr 7, 2024 · GA-ASI’s Eagle Eye radar with Video Synthetic Aperture Radar (SAR) enables continuous collection and processing of radar data and persistent observation of targets day or night and during adverse weather conditions By Phoebe Grinter / 07 Apr 2024 Follow UST
WebJul 31, 2024 · The video synthetic aperture radar (ViSAR) is a new application in radar techniques. ViSAR provides high- or moderate-resolution SAR images with a faster frame rate, which permits the detection of the dynamic changes in the interested area. A moving target with moderate velocity can be detected by shadow detection in ViSAR.
