The most important method to counter radar jammers is operator training. Any system can be fooled with a jamming signal but a properly trained operator pays attention to the raw video signal and can detect abnormal patterns on the radar screen. The best indicator of jamming effectiveness to the jammer is countermeasures taken by the operator.
Portable jammers are phone-sized and low-powered devices. They can block data delivery at a distance up to 15 meters without barriers. Stationary jammers are more expensive and powerful. They usually have a larger jamming radius and wider frequency band. Strong jammers can require additional cooling as they can overheat.

A bucket hat (variations of which include the fisherman's hat, Irish country hat and session hat) is a hat with a narrow, downward-sloping brim. Typically, the hat is made from heavy-duty cotton fabric such as denim or canvas , or heavy wool such as tweed , sometimes with metal eyelets placed on the crown of the hat for ventilation.

To counteract this filtering, the JAFF or CHILL technique has been developed. This uses an additional jammer broadcaster on the aircraft to reflect a signal off the chaff cloud that has the proper frequency to match that of the aircraft. This makes it impossible to use Doppler shift alone to filter out the chaff signal.
