Abstract:

Calculations describing the ionospheric propagation of high-altitude electromagnetic pulses EMP to satellite altitudes are reported. Both tangent and buried burst scenarios are treated. The calculations are based on the AFWL CHEMP code for self-consistent calculations of radiated EMP, modified by the inclusion of a swarm treatment of secondary and ionospheric electrons. The region of applicability of this swarm treatment has been determined by a separate Monte Carlo calculation. By carrying the calculations all the way from the burst point through the E region, the authors are able to account fully for the D region heating, the increased absorption and cascading it produces, and the increased cutoff frequency which results. The code calculations are evaluated for sensitivity to the ambient ionospheres used. Author
