This paper will discuss inadvertent electromagnetic compatibility issues between communication systems, electrical components in tactical vehicles. These inadvertent electromagnetic interferences (EMI) are attributed to the potential system performance degradation to communications. This paper will provide a practical engineering approach to mitigate EMI issues. Traditionally EMI issues were dealt with by applying Military Standards (MIL-STD). However, it is important to point out that meeting these MILSTD on individual system level doesn’t necessary imply system integrity is maintained when integrated with other systems. The integration of multiple systems in a common platform is why EMI issues must be evaluated as integrated by a different approach. The EMI mitigation techniques discussed in this paper should be adopted by integrators as standard practices and procedures used during development and integration of new tactical vehicles. In summary this paper will highlight engineering solutions to help lower EMI emissions and develop good practices to be implemented in the family of tactical vehicles.
