PAGE TITLE
Overview
PAGE SUMMARY
This technology describes a reactive jamming Software-Defined Radio (SDR) apparatus designed to target Frequency Hopping Spread-Spectrum (FHSS) signals. The apparatus consists of a peripheral SDR processing module, a reactive jamming hardware IP core implemented on a Field Programmable Gate Array (FPGA), and a host computer for non-time-critical operations such as configuration and strategy composition. The system utilizes band pass filters, energy detectors, and a jamming controller to disrupt FHSS signals based on detected energy thresholds. The reactive jammer is specifically designed for real-time operations, leveraging FPGA for time-sensitive tasks.
