The focus of this paper is on detection, tracking, confirmation and velocity estimation of moving targets in single-channel SAR images. Detection of moving target relies on a technique named doublet detection, while tracking is based on velocity estimation in the range-Doppler plane; confirmation of the target as a mover is enabled by two specifically developed tests on the range-Doppler target path. Velocity estimation is performed through a theoretically derived formula. The method and the results of extensive testing on real images are presented and discussed. © VDE VERLAG GMBH · Berlin · Offenbach.

The limited knowledge about the majority of the Mercury surface leaves many open questions regarding its geological evolution, the anomalously high metal/silicate ratio, the magnetic field generation and exosphere evolution. An integrated suite of instruments, Spectrometer and Imagers for MPO BepiColombo-Integrated Observatory SYStem (SIMBIO-SYS), which includes a stereo imaging system (STC), a high-resolution imager (HRIC) and a visible-near-infrared imaging spectrometer (VIHI), has been selected for the ESA BepiColombo mission to Mercury. SIMBIO-SYS will scan the hermean surface with the three channels and map the physical, morphological, tectonic and compositional properties of the entire planet. The availability of high-resolution images will unveil details of specific target at an unprecedented resolution. The main scientific objectives and performances along with technical characteristics of SIMBIO-SYS are described in this paper. © 2009 Elsevier Ltd. All rights reserved.

Recent improvements in CCD technology make hexagonal sampling attractive for such applications as remote sensing where the acquisition process is crucial to preserve image quality without introducing data transmission overheads. In the following hexagonal sampling is analyzed under general assumptions and compared with conventional rectangular sampling. The analysis takes into account both the lattice form (square, rectangular, hexagonal, regular hexagonal), and the shape of the single detector element. The hexagonal grid is not based a-priori on a regular hexagon tessellation, i.e., no constraint is made on the ratio between the sampling frequencies in the two spatial directions. © 2002 EUSIPCO.

The metrological traceability of meteorological measurements has become a mandatory requirement after the signing of the CIPM* MRA  by the World Meteorological Organization. Starting from the traceability requirement, a network of meteorological stations located in urban areas has been designed in order to obtain measurements useful for the energy balance determination. The chance of deciding which type of sensors to use, which QC/QA procedures to take, how to configure the database without any constraints of adapting to existing stations and facilities, has also made easier the task of controlling the vast amount of real time measured data from the new meteorological network. The network, named "Climate Network", has already 12 stations working in the province of Milan; it will consist of about 80 stations throughout the country within 3-5 years. The following presentation explains the "Climate Network" design criteria and the first results of the QC/QA activities. © 2011 IEEE.

Measurements of the refractive index of two different Lithosil samples and a sample of Suprasil 312 at cryogenic temperature and at 293 K are reported for the spectral range from 480 nm to 894 nm. Such data are useful for the design of fused silica optical components and systems destined for space missions. © 2010 BIPM & IOP Publishing Ltd.
