Description: A study of the effect the atmosphere has on anomalous  propagation is performed on an active radar fire  control/guidance system operating around 13 GHZ and a passive  Electronic Support Measure (ESM) countermeasure (CM) system  designed to detect signals in the 600 MHZ range. Atmospheric  conditions for three different areas of the world were  examined: the Persian Gulf, the Indian Ocean and the  Caribbean. Also demonstrated were the different effects  horizontally homogeneous and inhomogeneous atmospheric  profiles can have on electromagnetic (EM) systems. A  comparison with a standard atmosphere was done for both the  radar and the ESM system to illustrate the effect ducting  conditions have on extended signal strength.
