METHODS OF CREATING DIRECTIONAL ELECTROMAGNETIC INTERFERENCE FOR SELECTIVE INFLUENCE ON GPS/GLONASS: A REVIEW
Directional electromagnetic interference (DEMI) is an advanced method for selectively influencing Global Navigation Satellite Systems (GNSS), such as GPS and GLONASS, by generating controlled disruptions in targeted locations or frequency bands. The ability to precisely control electromagnetic interference is essential for applications in electronic warfare, cybersecurity, and controlled testing of GNSS vulnerabilities, where traditional wide-area jamming techniques may cause unnecessary collateral disruptions.
