This thesis represents a possible method for remote imaging called the Inverse
Synthetic Aperture Radar. A suitable algorithm based on this method is capable of
create two-dimensional image from a moving object. During this semester I learned
the physical background of remote sensing, especially the theory of imaging radars.
I had an oppurtunity to study a working radar system. I wrote a MATLAB script
to process the recorded les of the radar.
The rst chapter is an introduction to the physical background needed for understanding
imaging radar systems, such as SAR or ISAR. This chapter contains the
radar-equation, the Doppler-eect and the principles of synthetic aperture.
The second chapter deals with the radar equipment developed in 619. laboratory
of Department of Broadband Infocommunicatons and Electromagnetic Theory at
BUTEs Electrical Engineering Faculty. I examined the capabilities of this radar
creating ISAR images.
The third chapter explains the signal processing algorithm realised in MATLAB
for creating ISAR images from recorded data. At the and of the chapter, I present
some notable further development capabilities.
The appendices contain the MATLAB scripts plotting function-curves during the
theoretical introduction and the source code of the processing algorithm.
