通过将数字波束形成技术、多孔径信号处理等新兴技术与合成孔径雷达系统结合,国内外提出了多种新型的合成孔 径雷达系统,有效提升了微波成像的性能。文中重点介绍了新型合成孔径雷达系统中涉及的新原理和新概念,国外近些 年在新型高分宽幅合成孔径雷达系统的系统性能和成像模式,最后对新型合成孔径雷达系统走向实用化过程中必须克服 的关键技术进行了梳理和归纳。

Many new type of SAR is emerged to improving the imaging performance of synthesize aperture radar (SAR) significantly by combining some new technology, such as the digital beam forming technology and multiple aperture process. The special attention to the new principle and concept in SAR is paid in this paper. In additional, the system performance and the imaging mode of High-resolution Wide-swath SAR system are shown, at last, the key technology for the realization of new concept in SAR is given.
