Platform motion compensation method of airborn SAR

摘要

The method involves projecting measurement points and values on the real flight path onto the ideal flight path and computing the superposition of elementary waves on one or each point on the ideal flight path; the elementary waves starting point lies on a section of the real path corresponding to the section seen by an antenna with a given aperture angle located on a given point on the ideal path in a given main viewing direction. The method involves projecting measurement points (R') and associated measurement values on the real flight path (1) of the flying body onto the ideal flight path (2) and computing the superposition of elementary waves on one or each point (R) on the ideal flight path, whereby the starting point of the elementary waves lies on a section of the real flight path corresponding to the section seen by an antenna with a given aperture angle located on a given point on the ideal flight path in a given main viewing direction.
