This is a cooperative work between the Chair of Photogrammetry and Remote Sensing of ETH Zurich and the Research department of Ordnance Survey, called “Quality Assessment of 3D Building Data”. The project aims to derive methods to calculate metrics for the quantitative evaluation of 3D building models, which are assumed to be basic elements of a given 3D city model. The developed metrics should...

Neutrons pass relatively easily through matter and have been used successfully to interrogate the earth for bulk presence of elements, most notably those indicating petroleum. Applying these technologies to explosive detection is challenging because the “bulk” one is looking for can be as small as 100 g or less. The signals from 100 g of material are dwarfed by the background from the rest of t...

Emerging applications in Defense and Security require sensors with state-of-the-art sensitivity and capabilities. Among these sensors, the imaging spectrometer is an instrument yielding a large amount of rich information about the measured scene. This powerful spectrometric tool is becoming more common in civil applications such as search and rescue, geological surveys, pollution monitoring, fo...

We propose statistical processing methods and performance analysis techniques for discrimination and localization of Unexploded Ordnance (UXOs) using EMI sensors based on nonparametrically defined prior probability density functions for target-relevant features. In the first part of this thesis, new sets of UXO discrimination methods using these nonparametric prior models are introduced where w...

A rigorous method-of-moments (MoM) analysis is used to model wide-band scattering from general three-dimensional perfectly conducting objects buried in a lossy layered medium. Here, we focus on ordnance buried in a half space (soil). The time-domain fields scattered from a tilted antitank mine are examined in detail as a function of polarization and observation position.
