I would think with the recent radiation news from JApan that there would be a renewed awareness of this even greater risk of high power microwave....................
There were cases of increased cancer cases in a USA embassy somewhere in Russia......Cold war years............where we discovered there was a high power microwave dish , 20 footer, pointing right at the building. It was several blocks away IIRC..................any truth to that???
This was copy paste from:
http://blockyourid.com/~gbpprorg/mil/inter/index.htmlSince the late 1940s, the U.S. embassy in Moscow has been under a constant barrage of high-powered microwave energy. Conspiracy theories aside, the idea is that audio within a target embassy office will cause various nearby items to "vibrate," and any reflected microwave energy will also become modulated with this audio. The surveillance receiver is essentially phase demodulating the Doppler shifts induced onto the microwave signal by the slight physical motion of these objects. It works by mixing the received RF signal with a portion of the transmitted signal and greatly amplifying the final output. Modern devices of this type, operating at millimeter wavelengths in the 60+ GHz range, can literally fit in the palm of your hand. Information on their operation (and manufactures) leaks in from the "black" world when you study remote heartbeat monitoring equipment. One advantage to using millimeter wavelength microwave energy is the very narrow beamwidth (and high ERP) you can obtain. This will allow you to sweep the target location for any audio "sweetspots."
