I am interested on the effect of a HANE (High Altitude Nuclear
Explosion) ionization effect (not EMP)on UHF to SATCOM frequencies up
to 300GHZ. There was a naval experiment called Project Argus back in
the late 50's investigating the effect of a HANE on radio
communication and radar. Of course, back then no one was using UHF
and SATCOM.

Except from a document dating back from the 80's dealing with MX-1 C3
which was very vague, there is not much data on this phenomena.

Hi OM,

Try searching:
http://www.airpower.maxwell.af.mil/

A good search term might include "Electromagnetic Bombs" (E-Bomb)
which relate to this field of your interest.

Another sidebar might be found at:
http://www.haarp.alaska.edu/
which is the HIGH FREQUENCY ACTIVE AURORAL RESEARCH PROGRAM
This group would study the effects you speak of, and possibly generate
them as well, although not by nuclear means.
