Abstract : The purpose of this manual is to introduce the reader to a variety of effects that the lower atmosphere (troposphere) has on the performance of many naval electromagnetic (EM) systems and to describe the use of the Integrated-Refractive-Effects Prediction System (IREPS) Revision 3.0. The effects of concern here are only significant at EM frequencies above 100 megahertz (MHz) and, therefore, capable of affecting radar, ultrahigh, frequency (uhf) and microwave communications, electronic warfare, and missile guidance systems. The effects of the ionosphere has on high frequency (hf) communications, or other systems, are specifically not included in this document. IREPS has been developed, and is continuing to be refined at NOSC, to give a shipboard environmental-data processing and display capability of comprehensive refractive-effects assessment upon naval surveillance, communications, electronic warfare, and weapons guidance systems. IREPS has been successfully used under operational conditions aboard most CV/CVNs to assess the exploit refractive effects in a tactical situations. Prior to describing the products and operation of IREPS Revision 3.0, a background discussion of refractive effects, their causes, and resulting benefits or detriments to naval EM systems is presented.
