Electronic warfare planes can map invisible radar networks

In the invisible chess match of modern warfare, aircraft like Japan’s EC-2 function as high-altitude scouts that hunt for the very signals meant to destroy them. Instead of simply reflecting radio waves, these planes use sensitive receivers to 'sniff' out enemy radar frequencies across multiple bands. By measuring the exact power and pulse of these signals, the aircraft builds a three-dimensional map of the electronic battlefield, identifying exactly where a battery is hidden before it even fires.
