real-time simulation for verification of tactical electronic warfare system
In recent years, electronic warfare (EW) systems have become more and more reliant upon digital technology. Usually they include a digital computer with appropriate software programs used to control the various functions of the system, analyze EW signals, and in some cases, command the countering of the same signals. One of the first digital systems, truly software programmable, is the F-15 Tactical Electronics Warfare System (TEWS). The AFAL developed F-15 TEWS Automatic Airborn Weapons System Test Central provides capability for total and complete validation of the TEWS software performance under various threat environment conditions. These capabilities include: a. Static simulation of various threat radars; b. Dynamic simulation of dense threat environments and command and control functions; c. Real-time data collection and data reduction; d. Assembly and debugging of any part of the TEWS operational flight program (OFP); e. Linking various assembled modules with others from the library and loading the total program; f. Generate paper punch tape with the OFP for loading other F-15 TEWS. This paper identifies the set of programs comprising the real-time dynamic simulation, the operation of the real-time simulation model and data collection, and their application in the validation of the F-15 TEWS. In addition, the design methodology used is discussed as an effective tool to reduce programming time and simplify changes to the program.
