本文综述了用于宽波段高分辨率成像的多通道SAR系统的先进概念。介绍了几种采用直接辐射阵列和由数字阵列馈电的反射天线的新型系统架构，并对它们的成像性能进行了比较。此外，提出了创新的SAR成像模式，实现了高方位角分辨率的超宽区域的测绘。与terasar - x、ALOS、Radarsat-2或Sentinel-1等最先进的SAR传感器相比，这些新技术和新技术有可能将未来SAR系统的成像性能提高一个数量级。
This paper reviews advanced multi-channel SAR system concepts for the imaging of wide swaths with high resolution. Several novel system architectures employing both direct radiating arrays and reflector antennas fed by a digital array are introduced and compared to each other with regard to their imaging performance. In addition, innovative SAR imaging modes are proposed which enable the mapping of ultra-wide swaths with high azimuth resolution. The new techniques and technologies have the potential to enhance the imaging performance of future SAR systems by one order of magnitude if compared to state of the art SAR sensors like TerraSAR-X, ALOS, Radarsat-2 or Sentinel-1.
