Nuclear electromagnetic pulse penetration analysis in combat vehicle

The narrow width, large amplitude and fast rise time electromagnetic transient effect is of great concern to electronic systems. In this paper various coupling mechanisms of such an electromagnetic transient field in a combat vehicle platform are discussed. Efforts are made to mathematically model some of the coupling processes, predict and analyse the possible interaction levels inside the vehicle and also to evaluate the coupling of the transient through the communication antenna and the gun of the vehicle. The first level of an essential transient protection mechanism for the reduction of such high level transient fields has also been discussed. The exceptional contribution to the combat vehicle's EMC design implementation is acknowledged when it worked under various kinds of transients in India.
