对于传统的星载SAR，跨航迹方向的地面覆盖范围受到基本SAR操作约束和技术限制的限制。如果需要更大的覆盖范围，则必须考虑非常规的SAR操作模式。本文综述了一般的SAR波段加宽问题，并对各种波段加宽模式进行了描述。本文涉及概念性能，而不是技术实现，并专注于利用相控阵天线实现波束形成多功能性的系统。比较了各种方案的总体性能，并根据不同的性能要求对系统的选择提出建议。
For a conventional spaceborne SAR, the amount of ground coverage in the across-track direction is limited by fundamental SAR operating constraints as well as technological limitations. If wider swath coverage is required, then nonconventional modes of SAR operation must be considered. In the paper, the general SAR swath widening problem is summarised and various wide-swath modes are described. The paper deals with conceptual performance, as opposed to technological implementation, and concentrates on systems that exploit the beam-forming versatility made possible by utilising phased-array antennas. The various options are compared with respect to overall performance and suggestions are made as to system selection given different performance requirements.
