Investigation on an ultra–wide-swath, multiple-elevation-beam SAR based on sweep-PRI mode

Abstract

A promising candidate for ultra-wide-swath spaceborne synthetic aperture radar (SAR) imaging with a fine resolution is the multiple-elevation-beam (MEB) SAR. Conventional MEB SAR suffers from deterioration of noise-equivalent sigma zero (NESZ) and range ambiguity-to-signal ratio (RASR) performances in the far end of the imaging swath and disturbances… (More)
