" wrote: 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... |
