Efficient operation of probing radar in absorbing media

Abstract: A ground (or similar)--probing radar system in which the signal radiation is interrupted for short intervals. Reception is possible during these intervals and the dead range is virtually eliminated.

Broadband NDSHA computations and earthquake ground motion observations for the Italian territory

Abstract: The aim of this work is two-fold: 1) to compare the results of national scale NDSHA modelling for the Italian region at 10 Hz cut-off, based on the relevant available knowledge, with observations (eg, peak ground motion values) and existing empirical attenuation relations; 2) to update the scaling law for source spectra (SLSS) to be used for the selected area The new set of source spectra, defined along the lines suggested by the comparison with empirical attenuation relations, produces acceptable results in terms of PGV and spectral acceleration at long periods Synthetic PGA and SA at short periods show a faster attenuation with respect to the observed ones and, therefore, the effect of complex attenuation factors should be explored in future ad hoc studies

Hand-held Radar Device With Direct Printing Based on Radar Input

Abstract: The disclosed technology includes a device and method of use for direct printing and ink or other marking, in conjunction with GPR techniques. In a most basic embodiment of the disclosed technology, a relevant date, time, filename, and other parameters are printed or otherwise physically exhibited on the measurement surface, so that RADAR files can be later attributed to a specific data collection site. In a more advanced embodiment of the disclosed technology, actual RADAR target information is printed, or otherwise physically exhibited, on the measurement surface, such as while measuring, or substantially while measuring, the surface and substrate beneath with GPR.
