Compared with conventional synthetic aperture radar (SAR), video synthetic aperture radar (ViSAR) has attracted much attention due to its ability to perceive the dynamics of ground observation scenes. Among them, terahertz video synthetic aperture radar, in addition to reflecting the characteristics of the observation scene in the terahertz band, also has the potential to achieve higher imaging resolution and frame. At present, several relevant research has been carried out on terahertz ViSAR target detection or tracking methods. In the practical application, it is also necessary to realize a real-time data processing method that matches its imaging rate. However, there are few reports on this aspect. A real-time processing method for airborne terahertz video SAR data is proposed, achieving image registration, moving target detection, target tracking and target localization. When deployed on a Huawei Altas 200I DK processing board, the average processing time is 0.286s for one frame with a pixel size of 1024 × 2048.

摘要

Compared with conventional synthetic aperture radar (SAR), video synthetic aperture radar (ViSAR) has attracted much attention due to its ability to perceive the dynamics of ground observation scenes. Among them, terahertz video synthetic aperture radar, in addition to reflecting the characteristics of the observation scene in the terahertz band, also has the potential to achieve higher imaging resolution and frame. At present, several relevant research has been carried out on terahertz ViSAR target detection or tracking methods. In the practical application, it is also necessary to realize a real-time data processing method that matches its imaging rate. However, there are few reports on this aspect. A real-time processing method for airborne terahertz video SAR data is proposed, achieving image registration, moving target detection, target tracking and target localization. When deployed on a Huawei Altas 200I DK processing board, the average processing time is 0.286s for one frame with a pixel size of 1024 × 2048.
