The Challenges of Agile Mode Threats for Traditional Systems
Traditional radar and electronic warfare systems, based on static libraries, are increasingly tested by so-called agile mode threats. These threats exploit unpredictable frequencies and modulation techniques, as well as frequency hopping patterns that evade conventional threat databases. As a result, existing electronic protection and attack systems struggle to respond effectively, as they cannot quickly adapt to new threat configurations.
The Impact of AI/ML Technologies on Radar/EW Systems
Cognitive radar and electronic warfare systems, powered by AI and machine learning (ML), provide an innovative response to these challenges. Technologies such as artificial neural networks (ANN), deep neural networks (DNN), fuzzy logic, and genetic algorithms play a crucial role in the autonomous identification of threats. These systems enable signal deinterleaving and the creation of countermeasures in real-time, without requiring human intervention, thus offering unparalleled responsiveness to evolving threats.
The Architecture of Cognitive Radar/EW Systems
A cognitive radar or electronic warfare system relies on several essential functional blocks. RF acquisition, search and tracking, as well as AI/ML-based signal analysis, form the core of these systems. Carrier wave synthesis and RF generation complement this architecture, creating a closed-loop system capable of perceiving, learning, reasoning, and acting autonomously. This ability to operate without human intervention allows for rapid and effective adaptation to changing battlefield conditions.
Training and Validation of AI/ML Algorithms
To ensure the effectiveness of cognitive systems, the training and validation of AI/ML algorithms are essential. Wideband RF simulation and playback systems, combined with modeling and simulation software, enable iterative refinement of algorithms. These testbeds facilitate regression testing and mission preparation in controlled laboratory environments, ensuring that the systems are ready to face real-world challenges on the ground.
