Radar detection in maritime environment: Dependence on the radar antenna height in duct situations

Different meteorological conditions in maritime environment induce different optimal radar antenna heights to achieve a detection range as high as possible. Consequently the radar might be operated on an elevator moving along a mast. This offers the possibility to adjust the antenna height adaptively depending on the current atmospheric conditions. The possibility of utilizing an elevator moving along a mast and thus change the antenna position in height implies for the future for each site to require only one antenna instead of - so far - two antennas, one antenna about 40 - 60 m aloft and another so-called Duct-antenna at ground level to meet the Duct problem.
