1. A Two-stage Numerical Procedure for an Inverse Scattering Problem
Abstract : In this thesis we study a numerical procedure for the solution of the inverse problem of reconstructing location, shape and material properties (in particular refractive indices) of scatterers located in a known background medium. The data consist of time-resolved backscattered radar signals from a single source position. READ MORE

3. The Anticoincidence System of the PAMELA Satellite Experiment : Design of the data acquisition system and performance studies
Abstract : PAMELA is a satellite-borne cosmic ray experiment. Its primary scientific objective is to study the antiproton and positron components of the cosmic radiation. This will be done with unprecedented statistics over a wide energy range (~10MeV to ~100GeV). READ MORE

4. SAR Remote Sensing of Forests, from Microwaves to VHF
Abstract : The number of SAR systems available for civilian remote sensing purposes has grown in the nineties. A Synthetic Aperture Radar produces high resolution images of the earth independent on daylight and atmospheric conditions. This thesis mainly examines the applications of SAR remote sensing to monitoring forested areas. READ MORE

5. A Novel Signal Model and Estimation Method for Acoustic Doppler Current Meters
Abstract : This thesis deals with the process of estimating underwater current from the backscattering signal transmitted from an ultrasonic transducer. The narrowband sinusoidal burst signal is Doppler-shifted due to the current, and this information is converted into current. READ MORE
