Radar MIMO en présence d'erreurs de modèles : une approche par les bornes de Cramér-Rao

Dans cette contribution, nous étudions l'influence, sur les performances d'un radar MIMO, de l'erreur de modélisation du signal reçu. Pour cela, nous donnons des expressions analytiques de la borne de Cramér-Rao de l'estimation des paramètres d'un…

Back Projection Version of Subspace Detector SAR Processors

A new version of the signal subspace detector synthetic aperture radar (SSDSAR) processor developed in [1] is proposed. Actually, the SSDSAR processor can be divided in two different parts: a subspace basis computation part and an imaging part. The…

Effect of temperature and time on properties of Spark Plasma Sintered NiCuZn: Co ferrite

Spark Plasma Sintering is a powerfal method to produce fine grain dense ferrite at low temperature. However, the process, usually conducted in neutral atmosphere in a carbon die, yields carbon surface deposition and reduction of Fe3+ into Fe2+. It's…

Ageing defect detection on IGBT power modules by artificial training methods based on pattern recognition

The ageing of power insulated gate bipolar transistor (IGBT) modules is mainly related to thermal and thermomechanical constraints applied to the device. This ageing causes degradation of the device performances and defects appearance which can lead…

Grid Compliance of Ocean Energy Converters: Control Strategies and Recommendations

The potentially variable and intermittent electricity generated from wave and tidal energy may have some negative impact on the power quality of an electrical network. Impact assessment is usually performed by the use of power system simulators and…
