  • Radar Jammer, Interesting Project!!!!!

    In theory it is possible to write software that will do the following:

    1. It will know the speed limit for particular location and your current speed through the GPS on your car PC.
    2. It will scramble or diffuse the signal if you going over the speed limit and reflect back the appropriate speed.
    3. It will work on all frequencies and Laser equipment.

    I wanna hear your thoughts on this....

    I'd say that this is next to impossible, if not impossible. Despite the fact that there are 3 bands of radar, and one of Lidar, to jam radar takes a LOT. Let's take the Ka band for example. Ka covers a range of mhz that it can transmit on. So, no two radar guns will shoot out the same radar frequency. This means that you have to figure out which frequency is being used, generate the correct reply reflection, and transmit it back on the right frequency. To make things worse, you have to do this in nanoseconds or less. You have to remember that radar and lidar guns work off of time differential and distortion to determine speed. IMHO, it's not worth the time to even investigate.

      radar jamming (strawberry)

      I have worked with military equipment that does this. It is ungodly expensive and sophisticated. There may be some cheap simple way to do this, but it is not immediately apparent.

        I heard or read somewhere that the new F-22 raptor has jamming capabilities to augment it's existing stealth design. guess you could drive around with the nose cone from an F-22 strapped to your car...

          Jamming, sure. They'll either get wacked out readings or more likely no reading at all. But trying to send back a modified signal to make it look like you're going a specific speed, that's probably not going to happen even if it is possible.

          On a somewhat related note, this article is interesting. http://www.wired.com/cars/coolwheels..._cannonballrun
          These guys drove from Manhattan to Santa Monica in 32 hours and 7 minutes with an average speed of 90 mph. They made good use of radar/laser detectors and jammers.

                Hey, you have a plan there.


                What you need is a remote control plane controlled by the PC, which stays a constant distance in front and relays pictures from it's nose cam so you can monitor for smokeys

                  Till it plows into a highway sign. They'd probably charge you to fix it.

                    All of our signs are on the side of the highways. Billboards are illegal too. It would still be a cool video, would look like one of those tv guided bombs.

                      You guys are hillarious))
                      As the matter of fact everything is possible... As long as you have enough resources and time

                        It is illegal to transmit any radio frequency signal without a proper license, unless it is an unlicensed part of the spectrum. Radar falls with in the LICENSE REQUIRED part of the spectrum.

                        Now, whether it can be done, sure it can, but it won't be easy or cheap. Microwave transmitters are available, and can be made to "sweep" the proper frequency spectrum, but not for specific speeds, because speed is determined by time for rountrip and doppler shift.

                          Its not simple but not too hard to modify the echo and doppler shift. Someone already has a patent for this technology.

                          Here's some basic info for newbies:
