Abstract
We propose a method for determining layover areas during earth surface observation by a spaceborne synthetic aperture radar. Specifically, we construct a graph representing the distance from a satellite to a sampling point on the ground surface and use it to determine the existence of a span that overlaps with a length on the graph. If such a span exists, it will be extracted as a layover area. The efficiency of the proposed method is verified over a virtual terrain with known geometry and using the actual orbit path of the Advanced Land Observing Satellite-2, which is operated by the Japan Aerospace Exploration Agency.
