This paper presents a review of the time filtering methods to eliminate echo in antenna measurements. Two different methods, FFT and Matrix Pencil, are compared and simulated in a Planar Near Field (PNF) where other effects, such as aliasing, can happen if the simulation is not carefully carried out. Finally both time gating methods are applied to different real measurement of several antennas in...
Different research groups have been working during the last years in different echo reduction techniques applied to antenna measurements, based on spatial, modal or time filtering. Some applications where these methods are usually employed are: outdoor systems, for HF or VHF frequency systems or for small measurement systems where the anechoic material is only placed in front of the AUT. This paper...
Target identification presents severe technical complications even with nowadays technical capabilities. At INTA's Detectability Laboratory we have developed a synthetic stepped-frequency high resolution system with optical tracking and generation of frequencies configurable between 6 and 18GHz, which has been developed as part of a research project on non-cooperative target identification. The digital...
