Generation of Pseudo Time-Domain Holography from Frequency-Swept Measurements

This paper presents the methodology for generating pseudo-time-domain holography from frequency-swept measurements. This is an approximation to the time-domain holography (TDH) patented by the authors (J. Marti-Canales et al., 2000, J. Marti-Canales et al., 2002). It opens new possibilities for antenna diagnostics using conventional instrumentation, in the absence of time-domain measurements. Practical examples using two spaceborne antennas are provided and discussed.
