Clutter heterogeneity caused by cultivation variation of the terrain properties degrades STAP detection performance. In recent years, a priori knowledge sources has been used directly and indirectly for STAP performance improvement. Monostatic radar systems are typically considered, but in the bistatic case, strong clutter non-stationarity introduced by the geometry makes convetional STAP not possible...
The High-Luminosity phase of the Large Hadron Collider at CERN (HL-LHC) poses stringent requirements on calorimeter performance in terms of resolution, pileup resilience and radiation hardness. A tungsten-CeF3 sampling calorimeter is a possible option for the upgrade of current detectors. A prototype, read out with different types of wavelength-shifting fibers, has been built and exposed to high energy...
IMCP is an R&D project aimed at the exploitation of secondary emission of electrons from the surface of microchannel plates (MCP) for fast timing of showers in high rate environments. The usage of MCPs in “ionisation” mode has long been proposed and is used extensively in ion time-of-flight mass spectrometers. What has not been investigated in depth is their use to detect the ionizing component...
Moving targets appear defocused within SAR images and their detection is a challenging especially in the case of targets embedded in strong clutter. Moreover, in bistatic geometries, the clutter echo returns are range dependent. This situation degrades significantly STAP performance. In this paper, an adaptive compensation to homogenize data is performed first. This operation allow the proposed Space...
Moving targets appear defocused within SAR images and their detection is challenging especially in the case of ground targets that are embedded in strong ground clutter. STAP methods show optimal results in the clutter and interference suppression when the signal environment is stationary. This improves detection performance and allows for the application of ISAR based techniques which are then used...
The surveillance and control of maritime traffic, along with the management of wide area, such as ports and costs, need of the cooperation and coordination of manifold actors. The capacity of efficiently putting in place proper activities allows improving the safety and security of maritime transport forecasting promptly dangerous situations, collisions and threats, such as crossing of the boats close...
Grouping of a set of SSR Mode S stations into functional entities called clusters has significant operational facets; it calls for a constrained optimization, an important significant constraint being the scarcity of Interrogation Identifier codes. This problem can be approached by two ways, i.e., integer programming methods and heuristic approaches. The definition of a general, usable decision support...
