    The TACAN is located where there is no obstruction to its line-of-sight coverage. When it snows, its radome, particularly its windward side is covered with snow. This partial snow attaching on the radome causes azimuth error of the TACAN. In this paper, a simple computer simulation for estimation of the azimuth error caused by such snow attaching is proposed. Then we checked the simulation results against the test results of the azimuth error due to pseudo ice/snow layer and the results of measurements in the fields. Finally, we propose a spherical radome to alleviate this problem and its test results are presented. We think that this study is also applicable for radar antennas.
