This paper deal with the time delay removal of an Archimedean spiral antenna which operates from 400 MHz to 4845 MHz. As it is known, spiral antennas show a dispersive behavior, thus, in time domain, a "chirp" pulse will be displayed at the output. For time delay removal two proc

Among other applications, ulttrawideband systems, specifically radar systems, are used for antipersonnel landmine detection. Usually, these systems work from some hundreds MHz till GHz such to have both deep penetration and high resolution. As in any other electronic device the a

This paper refers to a special type of antenna, called frequency independent antenna, used in Stepped Frequency Continuous Wave (SFCW) radar employed for humanitarian demining. The radar transmits 128 frequencies within the frequency range from 400 MHz to 4845 GHz in groups of 8

Ground Pemetrating Radar for humanitarian demining has a large bandwidth. It should discriminate small objects against a complex background. The Stepped Frequency Continuous Wave radar of IRCTR has a synthesized bandwidth of 4.5 GHz. Classical methods for generating an image of t
