High-resolution wide swath (HRWS) and sustained imaging is of great significance in many fields, like public security, disaster warning, etc. Conventional airborne SAR is capable of high-resolution narrow swath imaging while spaceborne on the contrary[1, 2].
As such, this paper focuses on the role of near-space vehicle for high-resolution and wide-swath SAR imaging, and deals with conceptual performance, as opposed to technological implementation.
Thus, compared with spaceborne and airborne SARs, near-space SAR can provide a more flexible choice between azimuth resolution and swath width for satisfy the high-resolution and wide-swath imaging.
We examine likely effects of pixel-wide along-track sampling on climatological means of aerosol optical thickness (AOT) derived from observations with satellite instruments such as CALIOP and APS by sub-sampling AOT retrievals from a wide-swath imaging instrument (MODIS).

In order to achieve the HRWS, sustained imaging, and overcome the inherent defect of contradiction between azimuth high-resolution and rang wide swath for the high-speed platform, NSLS-SAR and its imaging strategy are proposed in this article.
Performance of the example system given at the end of the article verifies the effectiveness of the proposed near-space low-speed SAR high-resolution wide swath and sustained imaging concepts.
