I'm not familiar with the EA6B and doubt it had "megawatt"
output powers. EW designed to interfere with receivers
generally don't need such high RF output powers.

Actually Megawatt Output Powers for Pulsed Radars are easily in the
range of most military Radars.......

Actually, NO. "Most" are not at over one-megawatt
peak pulse levels.

Do the "radar equation" or just do the two-way free space
loss and then subtract the varying reflections of the
target (way NOT uniform). That gets a reasonable
approximation of power levels involved.

A long-range ship search radar has high power. It must
because it has to "reach" over the radio horizon. [more
loss due to refractive bending and scattering effects]

Intruders and Prowlers (E6 family) operate at altitude.
Their direct radio horizon is much farther due to that
altitude in comparison with a surface ship.

Electronic Warfare suites concentrate on copying the
enemy signal and returning it AS IF it were a target
return, either there or some distance away or on either
side. Only HALF the RF path is involved and the EW-
originated signal is quite low in level. Again, do the
"radar equation" but only the return path.

"Jamming" with over-much RF power went out with WW2.
It is much more subtle now and has been for years.
The circa 1958 MacDonnell Quail missle was a small
unmanned decoy air-breather with lots of automatic
radar futz-up on it. B-52s carried them then. I
worked a little bit on those at Ramo-Woldridge in
El Segundo, CA.

I'm also acquainted with the Association of Old Crows,
a professional one made up of those who work/worked in
Electronic Warfare. Try as I might, I can't remember
anyone there called "You." :-)

OK, let's get back to HOMEBREW things...
