Superstructure scattering distribution based ship recognition in TerraSAR-X imagery
Benefiting from the improved resolution and polarization information of SAR data, ship recognition has attracted much attention during the last decade. This paper considers the ship recognition in TerraSAR-X imagery. We propose a novel feature extraction algorithm, named Superstructure Scattering Distribution (SSD), by investigating the ship’s superstructure and corresponding electromagnetic sc...
متن کاملSonar Measurements in Ship Wakes Synchronous with Terrasar-x Overpasses
A pilot experiment was conducted by NSUOC and DLR in April-June 2008 in the Straits of Florida near Port Everglades, Florida in order to study the dynamics of far wakes of ships. In this experiment, a small boat with downward-looking sonar made “snake-like” sections through wakes of ships of opportunity during the TerraSAR-X overpasses. The ship identity and its parameters (length, speed, cours...
متن کاملSAR signature analysis for TerraSAR-X-based ship monitoring
It is expected, that ship detection and classification in SAR satellite imagery will be part of future downstream services for various applications, e.g. surveillance of fishery zones or tracking of cargo ships. Due to the requirements of operational services and due to the potential of high resolution SAR (e.g. TerraSAR-X), there is a need for composing, optimization, and validation of specifi...
متن کاملThe TerraSAR-X Mission
The German national SAR-satellite system TerraSAR-X is based on a public-private-partnership agreement between the German Aerospace center DLR and EADS Astrium GmbH. It is the continuation of the scientifically and technologically successful radar missions X-SAR (1994) and SRTM (2000) and is designed for scientific and commercial applications. The TerraSAR-X features an advanced high-resolution...
متن کاملShip Detection in Terrasar-x High-resolution Spotlight Dual-polarisation Imagery
This paper addresses ship detection in TerraSAR-X single-look high-resolution spotlight data by using a global thresholding approach, which is based on statistical analysis of the test data. The corresponding thresholds were determined separately from the exponential and chi-squared distributions for TerraSAR-X single-polarisation (HH or VV) and dual-polarisation (HH and VV) data. From the resu...
