A Parameter-Adjusting Autoregistration Imaging Algorithm for Video Synthetic Aperture Radar

IEEE Transactions on Geoscience and Remote Sensing, 2022
Video synthetic aperture radar (ViSAR) is gaining increasing attention in the remote sensing area due to its advantages in continuous observation compared with conventional synthetic aperture radar (SAR). Generally, the polar format algorithm (PFA) is utilized to generate the ViSAR frames considering both processing efficiency and imaging quality ...

Radar video generated from Synthetic Aperture Radar image

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
Synthetic Aperture Radar (SAR) can take a fine radar image without relation to sunshine condition. Recently, video generated from SAR is discussed. The radar video offers the practical understanding of the target motion without the added implement. The radar video is often generated from raw data in spotlight mode.

Aperture weighting technique for video synthetic aperture radar

Proceedings of SPIE, 2011
We present a technique for aperture weighting for use in video synthetic aperture radar (SAR). In video SAR the aperture required to achieve the desired cross range resolution typically exceeds the frame rate period. As a result, there can be a significant overlap in the collected phase history used to form consecutive images in the video. Video SAR
