Electromagnetic Compatibility of a Comprehensive Military Diver Combatting Installation with Nearby Radioelectronic Devices
The article deals witht hep roblem concerned with the effect the impulse electromagnetic field propagating from the electrohydraulic shock installation (EHSI) has on operation of the nearby radioelectronic devices. The problem of electromagnetic compatibility is extremely important for a llkinds of military forces, especially for warships, because they contain a multitude of radioelectronic devices and systems for various purposes within a very limited space. The impulse electromagnetic field distribution patternin the near-emission zone ofthe anti-sabotage electrohydraulic shock installation generating powerful electromagnetic impulse sisstudied. The EHSI application fields are classified in asystemati cmanner, and the operation principles of a particular EHSI adopted for service are considered. The performed analysis made it possible toreveal the key component serving as the main source of electromagnetic emission. The oretical dependenc esdescribing the distributions of magnetic and electrical field amplitudes as functions of the distance from the emission source are obtained. To verify the theoretical calculations, an experiment for determining the EMF induced in aerials from the impulse electromagnetic field generated by the considered EHSI was carried out. The graphs depicting the distributions of impulse magnetic and electrical fields trength amplitudes testify that the the oretical and experimental data are almost identical with each other.
