“…Also, the Research Institute of Microwave and Optical Communications (IRCOM) has designed compact UWB antennas capable of radiating high power pulses with a minimum of distortion, for applications such as transient radar cross section (RCS) measurements and UWB synthetic aperture radar (SAR) systems [3], [4] the "Scissors antenna" has these advantages and is described in the first part of this paper. For the first time, this type of antenna has been characterized in terms of gain, antenna factor and radiation pattern, by classical harmonic measurements in an anechoic chamber.…”

A new ultrawide-band (UWB) antenna named the "scissors antenna" has been designed specially for transient ultrawide-band applications. The scissors antenna, which is composed of conducting wires, radiates ultrashort pulses with very low dispersion. The radiation of this antenna has been characterized by a transient measurement method suitable for characterizing UWB antennas with very low dispersion. After a presentation of the scissors antenna, this measurement method is described. The last part of the paper presents a comparison between the radiation characteristics of the scissors antenna obtained by the transient measurements and those obtained by the classical harmonic measurements.Index Terms-Transient measurements, ultrawide-band (UWB) antenna.

Tripwire-operated fragmentation mines can be a significant hazard for deminers, especially during vegetation clearance. Several different technologies including thermal, acoustic, and electromagnetic have been evaluated as possible candidates for use in a reliable longrange detector which can find tripwires completely obscured by vegetation. An acoustic method has been proposed to detect non-metallic tripwires. The results of some experimental measurements using this approach are presented. Taut, non-metallic wires can be stimulated acoustically so as to generate a characteristic frequency component which may enable detection.

“…Since 1996, XLIM Institute has developed some Ultra Wideband (UWB) systems applied to Radar Cross Section (RCS) measurement [1] or UWB Synthetic Aperture Radar (SAR) like PULSAR for mines detection [2]. PULSAR system has shown difficulties to realize antennas which have a wide bandwidth [300 MHz-3 GHz] and can support high voltage (maximum peak level supply: 25 kV obtained in 2002).…”

Abstract-An ultra wideband radar system based on a coherent emission of an ultra-wideband antenna array using photoconductive switching devices is proposed. The triggering process is obtained by the excitation of semiconductor samples in linear mode using a picosecond laser source. The emitting antenna system and the receiving antenna developed by the Research Institute XLIM present some specific qualities suitable for radiation and measurement of ultrashort pulses. The optical control of the sources allows to sum the The experiments realized with this optoelectronic array validate these two concepts. Another way of improving these systems is proposed. It involves using bipolar pulse generators.
