In this work a new approach is proposed for the optimized design of a thinned array, based on a small set of different sub-array types (with assigned properties), properly disposed on a planar surface. The small number of different sub-array shapes is relevant for industrial production, to reduce design and manufacturing costs, as well as to allow scalable antenna designs for different applications...
In highly power constrained sensor networks, harvesting energy from the environment makes prolonged or even perpetual execution feasible. In such energy harvesting systems, energy sources are characterized as being regenerative. Regenerative energy sources fundamentally change the problem of power scheduling for embedded devices. Instead of the problem being one of maximizing the lifetime of the system...
Due to its high power levels provided, and its wide coverage, FM radio could be a good opportunity transmitter for passive coherent location (PCL) radar systems. In this paper we study the effectiveness of FM signals as radar waveforms by means of simulated and real data analysis. To this purpose, an emulation of FM radio transmitter is presented, whose outputs are compared with real FM data collected...
The paper aims at investigating different classification and segmentation tools for flood monitoring using satellite SAR images. To this aim, two different approaches, namely statistical segmentation and neurofuzzy classification are compared and discussed. The methods show, in general, the possibility to provide to a good extent accurate maps of the flooded areas using simple processing schemes....
