A lightning stroke presents a real challenge due to its potential to cause irreversible damage on electronics. Future systems are packaged in composite shielding materials, which give little or no protection with respect to the electromagnetic fields caused by a nearby strike. A direct lightning stroke is even a higher threat for densely packed electronics in composite housings. Our objective is to determine an appropriate level of protection for a direct stroke. From the military standard MIL-STD-464A - Severe Strike, peak currents of the discharge between 50 and 200 kA, for the A pulse, 2 kA for the B pulse and 200 to 800 Amps for the C pulse are re-created in a closed environment. Experiments have been carried out using a test setup that could duplicate these three discharge components on structures representative for radar housing.
