Abstract
The performance of radar and infrared systems in a maritime environment is strongly dependent on the conditions of the atmosphere and the sea surface. In the autumn of 1993 an experiment was set up by the NATO Research Study Group AC/243 Panel3/RSG21 to collect propagation data at a line-of-sight propagation path. The purpose of the experiment was to gain knowledge about the behavior of the path loss and angle of arrival of the signals. This paper presents the results of the Dutch contribution to the experiment and a comparison of the measurements with model predictions. For radar in the line-of-sight situation the propagation is dominated by the multipath interference and influenced by ducting. Predictions performed with the propagation model PCPEMC and the Bulk-CELAR duct model show satisfying results for the position of the nulls, if wind speed and wave height are taken into account. Using the data of this experiment, a synergism between radar and IR angle of arrival could not be proven.
