| Zusammenfassung |
| The aim of this work is to illustrate the results of Ground Penetrating Radar (GPR) and
passive seismic measurements in selected sites in Malta. The data were gathered during a
Short-Term Scientific Mission (STSM) performed under the COST Action TU1208 “Civil
Engineering Applications of Ground Penetrating Radar.” The purpose of the measures has
been twofold, namely to test the performances of an innovative GPR system [1], recently
upgraded, and to perform GPR and passive seismic analyses in several sites of interest in
Malta, in order to get an insight about their geological conditions as well as about the internal
status of some historical monuments.
The exploited GPR system was a prototypal stepped-frequency reconfigurable GPR,
implemented by IBAM-CNR together with the University of Florence and the IDS
Corporation within the research project AITECH (www.aitechnet.com/ibam.html). This
system contains three equivalent couples of antennas with the same gap, achieved from two
series of switches along the arms. The on and off state of the switches make equivalently
longer or shorter the antennas, so to achieve efficient transmission on three bands that
cover the comprehensive frequency range from 50 MHz to 1 GHz. Passive seismic
techniques where used in order to gather useful data to be compared and integrated with
those obtained with the GPR. Ambient noise was recorded using a three-component
seismometer.
Data were gathered at the following sites a) on a cliff area close to the Golden Bay tower; b)
Madliena tower; c) Laferla Cross; d) santa Maria Church. We were able to locate and
determine fractures on the cliff area as well as to locate graves and buried structures at the
investigated sites.
