Abstract :
Electromagnetic pulses radiated in the explosion of mild linear shaped charges are measured and analyzed. Signals are captured by a monopole rod and two dipoles, and recorded by a real time analyzer and an oscilloscope. After corrected by the antenna factor and applied the Hilbert transform, waveforms of the pulses are reconstructed. It is shown by the measurements that abundant of electromagnetic pulses can be produced in a chemical explosion. For mild linear shaped charges, width of pulses is about microsecond, and the amplitude may exceed 100 V/m. The results can be referenced for the design of electromagnetic pulse protection for aerospace electronics.
