Mechanical jamming is caused by devices that reflect or re-reflect radar energy back to the radar to produce false target returns on the operator's scope. Mechanical jamming devices include chaff, corner reflectors, and decoys.
Contemporary radar systems can distinguish chaff from legitimate targets by measuring the Doppler effect; [4] chaff quickly loses speed after leaving an aircraft, and the resulting shift in wavelength of the radar return can be measured. To counter this, a chaff cloud can be illuminated by the defending vehicle with a doppler-corrected ...
When jamming is strong enough, the radar receiver can detect it from a relatively low gain sidelobe. The radar, however, will process signals as if they were received in the main lobe. Therefore, jamming can be seen in directions other than where the jammer is located. To combat this, an omnidirectional antenna is used for a comparison signal ...
Interference techniques include jamming and deception. Jamming is accomplished by a friendly platform transmitting signals on the radar frequency to produce a noise level sufficient to hide echos. [1] The jammer's continuous transmissions will provide a clear direction to the enemy radar, but no range information. [1]

Chaff may be deployed over a large area of space, creating a large, radar-reflecting object that will obscure incoming warheads from defensive radar. Radar jammers are active radio transmitters that can be deployed on the decoys and the warhead to jam the frequencies used by defensive radars or literally blind them from seeing any warheads around.
Each offense of selling or using an illegal radio jamming device carries a fine of over $100,000, the FCC said. FCC investigating Amazon for reportedly selling illegal radio jammers Skip to main ...
