Re:Active Radar Jammer - 2006/04/20 23:48
Well, one of the things that work really well is pulling information from a signal that is below the noise floor. A good example is Voyager which is out at the edge of our solar system and broadcasting at less than 100mw. That signal is so far below the noise level you would not believe it but to this day Nasa is still in communication with it. Your TV remote is another good example, lot's of infrared noise floating around but the remote modulates the signal at 38 to 40 KHz which the receiver only looks for signals at that frequency. Anything else is filtered out.
Military systems jam radar signals by modulating at different frequencies and very high power but they are also blinded by their own jamming. Probably the easiest way to jam Ka band would be to find its frequency and return a phase shifted version of the signal back to the attacker. That way it throws off their timing signal and distance measurements. That is if they are not modulating the signal and embedding digital data in the signal.
Ok, that's really freakin' bizarre. How'd my post get ahead of the original poster? Or am I just seeing things?
