Wouldn't it make sense to use multiple receivers to drive jamming heads?

[shira9]

I don't know is to what extent PTs are a consequence of the receivers not detecting the incoming laser signal (and the jammers therefore not activating) OR of the jammers just not being sufficiently powerful (or not transmitting a sufficiently broad jamming signal) to defeat the laser gun.

If it's primarily the former, then it seems like a lot of problems could be solved if there were an array of receivers (4? 6?) spread over the front of the car (rear, too), feeding into a cpu that drives the (physically separate) jamming heads. I don't know much about the electronics involved, but I'm guessing that the detection-electronics are a lot cheaper than the jamming-electronics; it this is true, then the additional cost of multiple receivers might not increase the overall cost-to-manufacture by that much.

Thoughts?

The effect has been clearly demonstrated in many tests. You can see in the IR videos that heads are not firing when the laser is not aimed close enough to them. That's why punchthrough on headlights is so common. It is also why some of us theorise that 4 Blinder heads > 2 LI heads. Not because of the cumulative power (since until this version, blinder heads fired individually, not together), but because more "eyes" to receive the laser equals a greater chance that the shot will be received, and will be answered by a head close to it.

One thing that the LI and the new Blinder heads have in spades is excellent jamming performance. On the other hand, their ability to detect extraordinarily weak laser beyond the outermost fringes of the laser beam's cone is less than spectacular, just as Stealth Stalker mentions. I should note that the new Blinder heads do seem to perform better in this regard. On the other hand, the ZR4 heads have superb laser detection performance yet are weak with regards to jamming performance. It just occured to me that if Blinder and Escort ever decided to partner up to produce a new jammer product which incorporates the best of both systems, features and interface options, then the result would be an unbelievably killer LED based jammer system!

I see what you did there, Blinder Guy

The lasergun not "seeing" the jammer transmitter is a bigger problem than the jammer receiver not "seeing" the laser. The receiver optics in these guns is very focussed to the area where the laserbeam hits the car. I believe this is the main reason for punch-trues at close distances. So adding more transmitters (LED or LASER) will be more effective.

I posted in another thread an idea I had about modular jammer heads, where the LEDs and sensor diodes could be individually placed in strategic locations on the car.

If the heads could be redesigned into a set of miniature "headlets" that each contain one sensing diode and one or two jamming LEDs, which are then wired into a driver module tucked somewhere under the hood (or trunk for rear installs), I bet punchthroughs could be all but eliminated with proper placement of the "headlets".

If the headlets are compact enough, some could even be mounted inside headlights, some tucked into the grill, some around the plate, and maybe even tuck a couple in the corners of the windshield or side-view mirrors for TOTAL coverage.

Also, the "headlets" could be stealthier than the much bulkier LED head assemblies used now. They would be great for rear installs, where there aren't as many places to hide heads.
