摘要
Kerr (MIT Rad Lab Vol. 13)对用于跨视界衍射传播场强计算的高度增益函数的图形近似进行了修改，以使其有效，假设波长为3米或更短，适用于所有表面介质，包括极化和低天线高度至零。这些改进对于低空电磁平台之间在海水上的VHF-UHF垂直极化传播尤为重要
VHF-UHF propagation performance predictions for low altitude communication links operating over water
The Kerr (MIT Rad Lab Vol. 13) graphical approximation for the height-gain functions used in trans-horizon diffraction propagation field strength computations are modified so as to be valid, assuming wavelengths of 3 meters or less, for all surface media, both polarizations, and low antenna heights down to zero. The modifications are particularly important for VHF-UHF vertically polarized propagation over sea water between low altitude electromagnetic platforms.<>
