Scattering and propagation impacts on shipboard radar systems

The tropospheric electromagnetic parabolic equation routine (TEMPER) has been used extensively in conjunction with system simulations in support of operational US Navy exercises and in various ship´s system design tradeoff studies. The theory, features, and performance of TEMPER are described briefly, followed by a discussion of atmospheric measurement and resolution issues. Two high-resolution measurement systems are reviewed. Radar system simulation using environmental information is discussed, and several performance predictions in postulated propagation conditions are presented. Finally, a prototype environmental assessment system designed for use on board AEGIS ships is briefly described
