Abstract
Results of computations and measurements for the radar cross-section of Canadian Navy tug Glenside are presented. The comparison between measurements and computations is good at some frequencies but not at others. The comparison is also not good around the bow of the boat because not enough details were built into the AutoCAD model. Both the computations and the measurements show a decrease of the RCS in the areas where the radar absorbing material has been applied, but only for a very narrow azimuth span of about 5°. A lot more details have to be added in the AutoCAD model in order to obtain a reasonable comparison between the measurements and the computations. In addition, the rocking motion (pitch, roll, and yaw) of the tugboat during the measurements is a possible cause of the discrepancy in the comparison. The motion of the boat has to be tracked during the measurements to get a better estimate of the RCS under various conditions.
