In order to allow quantification of the strength of local micro-seismic events recorded at the CCS pilot site in Ketzin in terms of local magnitude, earthquake data recorded by standardized seismometers were used. Earthquakes were selected that occur

In this paper we introduce a concept for monitoring and surveillance based on SAR imagery. A workflow for detection and characterization of changes is presented and discussed. SAR imagery is quite efficient for detection of changes, but less adequate

Improving small target detection in sea clutter is an important step towards making radar a more effective tool for coastal surveillance and infrastructure protection. Terrorist attacks at sea or coming from sea can be expected to be carried out with

The use of ISAR imagery for Automatic Target Recognition is seriously hampered by the difficulty of target motion compensation. Phase perturbations that result from target maneuvers during the processing interval need to be corrected for. In a previo

The aim of this project is to demonstrate to the Dutch armed forces the capability of MTI (Moving Target Indicator) and SAR (Synthetic Aperture Radar). This is done with the Dutch PHARUS sensor. The sensor is used to demonstrate how a phased array an
