Transient ultra wide band measurement applications: radar cross section, synthetic aperture radar, electromagnetic compatibility

The Electronic Armament Centre (CELAR: Centre d'Electronique de L'Armement) and the Research Institute of Microwave and Optical Communications (IRCOM: Institut de Recherches en Communications Optiques et Micro-ondes) has evaluated the use of ultra-wide-band (UWB) short pulse measurement facilities to characterize target electromagnetic signatures. A first device is capable of determining the radar cross section (RCS) within a 200 MHz to 1.2 GHz frequency band. A second device, an UWB synthetic aperture radar (SAR), is dedicated to pulse measurements on outdoor targets (buried mines) and low frequency clutter. These transient techniques are soon used for EM coupling applications on various systems.
