Electronic warfare - a form of military use of the electromagnetic spectrum 4 Radio electronic warfare is a type of armed warfare in the course of which radio emissions (radio interference) affect the enemy's radio electronic means of control, communication and reconnaissance systems, protect their systems from similar effects, as well as change the conditions ( characteristics of the environment) of radio waves propagation Main areas of improvement of electronic warfare means 1. Broadening the frequency bands of electronic suppression means 2. Multiple radiation variants 3. Cognition (presence of artificial intelligence elements, built-in logical control subsystems) 4. Adaptability 5. Modular concept 6. Open software architecture 7. Increased protection against the impact of enemy EW means

Managing the use of the radio frequency spectrum 5 Prospective planning for the use of RFS Ongoing planning for the use of RFS Ensuring EMC of RFS Managing the use of RFS Radiocontrol of the use of RFS Operational planning for the use of RFS International legal protection of REM

International regulation of the use of the radio frequency spectrum 6 International legal protection of REM - activities aimed at implementing a set of legal, organizational, technical and scientific procedures with the following objectives: defending the interests of the Armed Forces in the international redistribution of RFS, obtaining international recognition of the use of radio frequency bands (nominals), orbits and points of location of artificial Earth satellites from REM of military purpose by their registration in the ITU, as well as eliminating the impact of unintentional radio interference on REM of military purpose from REM of foreign countries International legal protection Defending the interests of REM of military purposes in the international redistribution of RFS Elimination of unintentional interference from REM of foreign states Obtaining international recognition for the use of bands (nominals) of frequencies, orbits and locations of ASE
