Surface currents imaged with hybrid along and cross trackinterferometry

摘要

Radar interferometry is known to be a useful technique for mappingterrain heights and surface currents. Several studies on along track orcross track interferometry provided highly accurate results. In the caseof coastal applications a simultaneous measurement of topography andsurface currents is beneficial. Therefore an approach for airborneinterferometric measurements with a baseline consisting of an along andcross track component is presented. Analysis of experimental airborneinterferometric data shows good results. The final accuracy is highlydependent on the accuracy of the navigation data of the aircraft
