SummaryWe propose to obtain new TerraSAR-X data covering the levee-enclosed islands of the Sacramento-San Joaquin Delta, the largest Delta on the Pacific coast of the American continents and the State of Californiaís most critical water resource.Our goal is to optimize transition the techniques that we have developed for levee monitoring with UAVSAR from the relatively expensive airborne acquisitions to a long-term monitoring satellite SAR solution that gives more comprehensive levee coverage in low temporal coherence areas. For TerraSAR-X, we require frequent acquisitions (11-day repeat interval) for 15 months.The study will include analysis with SBAS techniques to reduce the effects of temporal decorrelation using techniques developed for the UAVSAR levee study.To cover a large part of the Sacramento Delta and better image the landside levees, we require 4 scenes, two each on ascending and descending orbits.Similar temporal and spatial coverage of the area with UAVSAR will be collected over the same time frame, with funding for both UAVSAR and TerraSAR-X acquisitions already in place under P.I. Jonesís existing levee study projects.This request to DLR is for acquisition of 172 single-polarization, single-look complex TerraSAR-X products over a 15-month period beginning as soon as possible.This study builds on an approved proposal for access to DLRís archive products over the same area (MTH1604).
