Abstract:

The effect of the evaporation duct on maximum intercept range of 18- and 37.5-GHz emitters is modeled. Results show that ranges for high-power emitters or high-sensitivity receiver systems are greatly affected, while ranges for low-power emitters are not. Optimum shipboard receiver heights are determined for each frequency. Comparisons of some modeled results to observed data are included. Author
