Abstract

The system is a parallel processing jamming architecture that is designed to automatically attack and concurrently investigate multiple signals simultaneously in the radio environment. The system implements multiple wideband independent channels to allow simultaneous threat signals to be processed in parallel and jammed in real-time. The system automatically attacks a radio communication channel when the suspect radio signal surpasses a dynamic composite threshold which is internally updated using multi-channel data feedback, in real-time. The concurrent analysis with transmission allows the system to optimize the jam efficiency quickly to an unknown signal, and while determining the validity of the threat. The high throughput parallel architecture allows the intelligent jamming process to occur with rapidity and signal multiplicity.
