What is a Spot Jammer?
During the air war in Europe the Germans developed a radar assisted anti-aircraft battery. This allowed them to shoot at the planes above the cloud cover. In response the B-17 Squadrons deployed a radar jamming device called “spot jammer” to jam enemy radar. It consists of three transmitters and one receiver. As the receiver locates a radar signal, a transmitter will jam it. A spot jammer can jam up to three radar signals at one time.The spot jammer operator was specially trained to recognize the enemy radar signals and counter them.
