UWB short pulse sensor for target electromagnetic backscattering characterization

The Electronic Armament Centre (CELAR: Centre d´Electronique de l´Armement) has evaluated the use of a relatively low frequency ultra-wide band short pulse measurement facility to characterize target electromagnetic signatures. Specific measurement instrumentation has been developed and implemented. The initial measurement trial began at the beginning of 1998 and led to the establishment of a database on various targets. These measurements made it possible to interpret, in the time domain, the signatures and to work out holograms. Images were calculated either in the time or the frequency domain
