该文展示了世界上几个重要的先进混合双基SAR实验。混合双基模式是指发射端和接收端分别装载于不同类型的平台,例如星载/机载,机载/静止平台,星载/静止平台等。近年来相继有若干混合双基 SAR 实验成功完成,主要包括TerraSAR-X/PAMIR,PAMIR/静止平台,以及TerraSAR-X/静止平台。此外,在TerraSAR-X/静止平台的双基模式下还验证了多基线干涉 SAR (MB-InSAR)和数字波束形成(DBF)技术。值得强调的是,该文所展示的DBF实验结果属于世界上首次成功的基于在轨雷达卫星的DBF实验。

This study concentrates on the results of several advanced hybrid bistatic SAR experiments. The hybrid bistatic configuration applies to the case in which the transmitter and receiver are mounted on different types of platforms, e.g., spaceborne/airborne, airborne/stationary, spaceborne/stationary, and so on. Several hybrid bistatic SAR experiments have been performed successfully, i.e., TerraSAR-X/PAMIR, PAMIR/stationary, and TerraSAR-X/stationary. Furthermore, Multiple Baseline Interferometry SAR (MB-InSAR) and Digital Beam-Forming (DBF) technologies are validated in the TerraSAR-X/stationary configuration. Note that the DBF experiment results based on the spaceborne illuminator are discussed for the first time in SAR community. In addition, this paper emphasizes imaging geometry, image analysis, and focusing results.
