signal across the entire bandwidth, ensuring the signal is diluted. Combining this with extremely powerful signals and highly focused antennas allowed new radars to overpower the jammers, "burning through" the jamming. Simple techniques, like turning off the receivers when the antenna was pointed close to the jammer, allowed the radar to continue tracking other targets. The use of phased array antennas and signal processing techniques that reduced sidelobes also improved performance. Barrage jammers also have the disadvantage that they are very easy to detect using a wideband receiver. This can be used to track the jammer using a variety of techniques. A well developed instance of this was deployed by the RAF in their RX12874 network, which could track jammer-carrying aircraft with accuracy equal to a radar. More generally, a barrage jammer's signal is so easy to receive that it makes an excellent early warning signal on its own. See also Radio jamming References Electronic countermeasures
