U.S. Deploys Satellite Jamming System

CNN has an article about a ground-based satellite jamming system that "uses electromagnetic radio frequency energy to knock out transmissions on a temporary and reversible basis, without frying components". Is this just another old school EM jamming technique, or something new? Of course they won't say, citing "operational security" concerns.

    "Anti-radiation missile" is a military term for anti-radar missiles like the Shrike and HARM, or for EU types the ALARM. Doesn't have anything to do with nuclear radiation.

    Have you ever gotten those places on your FM dial, where it sounds like 10 different stations are coming in at once? That is intermodulation distortion. Very large signals competing with other very large signals. This is most likely what this "weapon" does. Just overloads the telemetry, data channels, etc of a satellite receiver. It takes alot of current to produce overload resistant receivers, and current is always at a premium on satellites, so I would expect weak receiver front ends that are subject to this ground interference.
