Developments in repeat pass interferometric radar for Earth and planetary sciences

Repeat pass radar interferometry has developed into a wide ranging geodetic and change mapping tool from space. For large areas of the Earth, and for numerous applications that demand more persistent monitoring, the true potential of the repeat pass technique remains largely untapped. While the research community has made enormous strides in extracting as much information as possible from existing data sets, fundamentally new observing systems are needed for breakthroughs in a number of areas. Repeat pass interferometry techniques applied on missions to the terrestrial planets, Earth´s Moon and the icy moons of Jupiter can reveal new insights in to the history of the surface and near subsurface.
