Abstract

© 2021 IEEE.The recent importance of simulation and modeling in Electronic Warfare Systems arises from its providing test an training opportunities without expenses and danger. In all known studies about EW simulation, only signal parameters such as radio frequency, pulse repetition interval, pulse width are used when modeling a threat. However, a real threat has maneuverability in 3D space. In this study, a threat platform modeling application in MATLAB is presented. Threat platforms and their antenna scan types (steady scan, circular scan, sectoral scan, raster scan, helical scan, scan, lobe switching) are expressed mathematically in 3-dimensional space using Euler Angles. The maneuvers of the threat platform are modeled using Rotation Matrices. By collecting the signals emitted by a threat in moving and fixed positions separately by the friendly platform, the differences between amplitude and phase values, which are important for direction finding and antenna scanning type detection algorithms, have been examined and the importance of maneuverability in a modeling has been proven.
