The U.S. Navy has been using a shipboard radar propagation assessment system for the past decade. The system was conceived as the Integrated Refractive Effects Prediction System IREPS in 1973 tested at sea in 1976 and installed on most capital ships beginning in 1978. IREPS provided two types of products 1 displays of refractivity data and 2 sensor performance displays. The workhorse display was the radar coverage diagram used by the air wing to determine penetration or jamming altitudes against hostile radars. This initial capability to exploit propagation effects was received so enthusiastically and proved so successful that the development of Tactical Decision Aids TDAs became part of an ongoing program to enhance this capability in the fleet. These TDAs structure the propagation information for the decision maker and perform functions that would otherwise overwhelm him. The decision maker is not directed to a specific course of action but rather is provided a framework within which he can make tradeoff decisions with respect to propagation in conjunction with other essential factors of his mission. This approach to the development of an aircraft stationing aid is discussed along with an overview of several TDAs applicable to various warfare areas. Efforts to incorporate these tactical decisions aids into Navy sea-based command and control systems are explored.
