We investigated the formation of microcrystalline silicon (μc-Si:H) epitaxially grown on the polysilicon seed layer on the aluminium(Al) substrate using Electron cyclotron resonance plasma enhanced chemical vapor deposition method (ECR-PECVD). The μc-Si:H film serves as an active intrinsic absorber layer for a PIN configuration solar cell. A seed polysilicon (P+) layer was created by depositing amorphous...
UAVs from different countries and with different payloads have proven their capabilities within military applications. Future UAV employment in the civilian areas of surveillance (pollution, natural risks prevention, fire prevention), monitoring (traffic control, environmental monitoring, earth observation) and communication relays becomes unavoidable. Many payload configurations may be used in UAV...
Following previous studies, a concept of low-cost imaging Ka-Band radar is presented in this paper. This radar is integrated into under-wings pods that are fixed on a STEMME S10VT motorglider. This radar concept combines real aperture in the cross-track direction, by the antennas geometrical aperture, and synthetic aperture in the along-track direction, realized with the aircraft motion. Radar front-end...
This article is concerned with the apodization windows to be applied to brightness temperature maps reconstructed from complex visibilities provided by the MIRAS (Microwave Imaging Radiometer with Aperture Synthesis) instrument on board the SMOS (Soil Moisture and Ocean Salinity space mission) spacecraft in order to achieve a close to uniform pixel at the Earth's surface level
