On the Challenges of Coherent Ambiguity Removal in the Harmony Mission

Kurzfassung

This contribution presents and concludes on challenges for the operational implementation of a coherent azimuth ambiguity suppression algorithm for the Harmony mission. This comprises a conceptual rework and generalization of the algorithms to arbitrary bistatic interferometric mission geometries including azimuthal variance and first experimental realizations and verification with real operational InSAR data acquired by the TerraSAR/TanDEM-X satellites. Challenges in terms of required parameter knowledge and sensitivity and error analysis are identified and quantified to shape the Harmony mission design and algorithm development process.
