A system concept for wide swath constant incident angle coverage
Abstract
The multiple beam SAR system concept is developed and shown to readily overcome the radar ambiguity constraints associated with orbital systems, thus permitting imagery over swaths much wider than 100 km. The antenna technique permits imagery at nearly constant incidence angles. When frequency scanning is used, the center angle may be programmed. The redundant use of the antenna aperture during reception results in lower transmitted power and in shorter antenna lengths in comparison with conventional designs.
