Through-Wall Imaging With UWB Radar System - KEMT FEI TUKE

Chapter 3
Goals of Dissertation
Investigation of the objects behind an opaque wall is a very promising field for a
rescue and security applications nowadays. However, through-wall imaging is still
a very young developing field based mostly on theoretical approaches. There are
only few works published recently showing real measurements results. It is obvious,
that the present methods are not ready for practical usage. Using conventional
methods in praxis leads to unprecise and distorted results. Moreover, most of
them uses extremely time consuming computations what obstructs to use them
in real-time applications. The way to introduce through-wall radars in real and
practical applications is very meander and still requires a lot of research in signal
processing as well as in radar hardware field.
Based on the previous analysis, our research would be concentrated on signal
processing and improvements of methods, that move through-wall radar field closer
to the practical utilization. We will be focused on methods that can be used in
realtime. The goals of the thesis can be summarized as follows:
• to develope an effective and precise method for estimation of TOA through
the wall that is required for precise migrations, with small computational
complexity that can be used for practical applications;
• to develope fast, precise, and easy to handle measurement method for estimation
of wall parameters required for precise TOA through-wall estimation
that can be used for practical applications;
• to develope an image processing method for highlighting the building contours
in order to enhance the wall visibility of a building scanned from the
outside;
