A Compressed Sensing Algorithm for Magnetic Dipole Localization

This paper proposes an algorithm to localize a magnetic dipole using a limited number of noisy measurements from magnetic field sensors. The algorithm is based on the theory of compressed sensing, and exploits the sparseness of the magnetic dipole in space. Beforehand, a basis consisting of magnetic dipole fields belonging to individual dipoles...

Toelichting PERSEUS radarhinder toetsingsmethode en berekeningen 2021

Radarsystemen ondervinden mogelijk hinder van windturbines of windmolenparken. Het Ministerie van Defensie heeft daarom normen opgesteld waartegen de prestatie van de luchtverkeersradarsystemen getoetst moet worden. Deze normen gelden voor zowel de militaire als de civiele luchtverkeersleidingsradarsystemen in Nederland, te weten de...

Model-aided Feature Extraction

The usage of radar system modeling in the radar resource manager (RRM) or in the resource manager of a suite of sensors is discussed. Multiple ways to monitor the validity of the models are identified. The capability of such models to predict estimated elevation angle under anomalous propagation conditions has been investigated. Satisfactory...

Multichannel imaging with the AMBER FMCW SAR

An X-band Digital Array Synthetic Aperture Radar for a Short Range Tactical UAV is presented. The Frequency Modulated Continuous Wave radar principle in combination with digital beam forming over 24 receive channels is used to achieve low power and advanced imaging SAR capabilities on small platform. Novel SAR imaging modes are discussed, and...

AMBER: An X-band FMCW digital beam forming synthetic aperture radar for a tactical UAV

An X-band Digital Array Synthetic Aperture Radar for a Short Range Tactical UAV is presented. This system is demonstrated on a manned helicopter and motor glider. The Frequency Modulated Continuous Wave radar principle in combination with digital beam forming over 24 receive channels is used to meet the stringent payload requirements of Tactical...

Maritime Situation Awareness Capabilities from Satellite and Terrestrial Sensor Systems

Radar Imaging of Building Interiors using Sparse Reconstruction

At TNO an innovative concept to obtain inside building awareness with stand-off, through-the-wall radar has been developed: SAPPHIRE. The system concept exploits particular phase behavior in the 3D radar data to extract dominant scatterers inside a building. These scatterers can be reconstructed from the data using an overcomplete dictionary and...

Radar Mapping of Building Structures Applying Sparse Reconstruction

The ability to map building structures at a certain stand-off distance allows intelligence, reconnaissance, and clearance tasks to be performed in a covert way by driving around a building. This will greatly improve security, response time, and reliability of aforementioned tasks. Therefore, through-the-wall radar systems supporting stand-off...

Radar Mapping of Buildings using Sparse Reconstruction with an Overcomplete Dictionary

At TNO a new concept to synthesize maps of building structures with stand-off, through-the-wall radar has been developed: SAPPHIRE. The system concept exploits particular phase behavior in the 3D radar data to extract dominant scatterers inside a building. The phase relations are extracted from the radar data by using an overcomplete dictionary...
