Continuously broadcasts white noise of high amplitude, causing radar guns to read random numbers, preventing a reading of the actual speed of the car. The radar gun takes about 8 measurements of speed, and only outputs a speed if the 8 measurements agree.
Advantages
- Always works except sometimes at VERY close range
- Very easy to build and operate, since it is always on
Disadvantages
- Very Illegal: Jamming or attempting to jam a police radar gun is a federal felony punishable by fines up to $75,000 and one year in jail.
- Very easy to detect, since you are broadcasting a loud signal to everyone around. Most modern radar guns have detectors for these signals, alerting the cop when he is being jammed in this manner.
- Radar detectors will not work, since your own jammer is constantly broadcasting radar anyhow.
- The cops can shoot an anti-speeder missile which homes in on your jamming signal.
