Stemming the EMI Tide in Submarines (Download)
Electromagnetic interference (EMI) may affect the performance of any onboard electronic systems in a submarine. Key points about EMI in these vessels include:
- Sources of EMI: EMI can originate from various sources, including onboard equipment, external electromagnetic fields, and even natural phenomena like lightning.1
- Impact on systems: EMI may disrupt communication systems, navigation equipment, and other critical electronic systems on a submarine. This can lead to malfunctions or degraded performance.2
- Mitigation strategies: To minimize EMI, submarines use shielding, grounding, and filtering techniques. Proper cable management and the use of EMI-resistant materials are also essential.3
- Standards and regulations: The Navy has specific standards and procedures for managing EMI, such as the MIL-STD-461F and MIL-STD-464C, which outline requirements for electromagnetic compatibility and emissions.4
- Technological advances: Modern submarines are increasingly using advanced technologies to detect and mitigate EMI, ensuring the reliability and safety of their operations.5
