Electromagnetic Environment Simulation Software Design and Its Application Using DRFM Techniques on Software Defined Radio

As electronic warfare (EW) becomes increasingly significant in modern battlefields, the demand for simulation environments in the development of EW systems rises. There is a strong focus on creating flexible and cost-effective systems to simplify the design process of electronic warfare systems. In this study, a generalized electromagnetic environment simulation software capable of simulating different types of Radars, Electronic Countermeasures (ECM) and Electronic Counter-Countermeasures (ECCM) is designed. The software can model radars and Digital Radio Frequency Memory (DRFM) based EW systems. Its open architecture structure allows users to input the parameters of radar and EW systems for modeling. A scenario-based interface is developed to provide users with flexible analysis capabilities. The performance of the software was tested using commercially available Software-Defined Radio (SDR) equipment to establish a Hardware-in-the-Loop (HIL) setup. Results from multiple scenarios demonstrated that the simulation software effectively implements EW techniques in accordance with the conditions and scenarios defined by the user. The key novelty of this work is the integration of radar and ECM simulation within a unified, scenario-based platform that supports real-time validation through Software-Defined Radio (SDR) hardware. This approach enables cost-effective and scalable Hardware-in-the-Loop (HIL) testing.
