Pay greater attention to the mobile speed effect

Existing radar often false positives, false negative, invalid broadcast plagued many users, as the most professional of good collar's high-end brand with unique Often use mobile speedometer friends all know, mobile speedometer false positives, false negative, invalid broadcast is more prominent, and most brands of mobile speed fittings are through OEM, so own their own technology accumulation and strength to improve these conditions. Be able to journey as a good collar and direct descendant of the brand with good neck strength and accumulation, to avoid the occurrence of these conditions. This is the journey of a unique the AFF intelligent filtering system.
Broadcast, to avoid unnecessary journey the AFF intelligent filtering system according to the speed intelligent judgment
Existing radar often false positives, false negative, invalid broadcast plagued many users, as the most professional of good collar's high-end brand with unique the AFF intelligent filtering technology can effectively solve the false positives, false negative, invalid broadcast the current industry other brands can not solve the problem. AFF intelligent filtering through the GPS built-in memory is stored a road speed limit value of the car through a section of the positioning information provided by GPS satellites, the early warning instrument than the current road speed limit and current speed. If the current speed below the speed limit value, you automatically filter out all radar signals.
If the current speed exceeds the speed limit value, in accordance with the signal waveform, if the judgment is a valid signal, the instant of radar speed warning. Intelligent filtering the interference signal, to solve the embarrassment and distress of the disorder reported daily electronic dog. Exclusive range early warning, to solve the problem of the interval can not be guns and warning. The usual speed measurement radar "speed" interval speed "is the calculation of the vehicles average speed over the range, to screen the vehicle is speeding. For such a tachometer designed interval speed warning function. Changed the status of the interval speed "can not warning. Achieve a single point, the perfect combination of range warning.
Journey the AFF intelligent filtering system to solve the speed radar biasing phenomenon
We compare the well-known signal consists of K band, KA frequency, KU frequency laser, in which the KU-band is the European standard, the laser is actually LASER, the velocimetry band a. At present, our country is the U.S. regulations and European regulatory standards. This band is the most commonly encountered.
The main range of the K-band 24.150 GHz, plus or minus about 100MHz. KA band range is between 33.40 to 36.00GHz. As we all know, electronic products, this stuff a long time can not be constant quasi tachometer, thus leading to a lot of speed radar frequency after a long time, partial frequency phenomenon, such as the normal K frequency should be 24.150 plus or minus after the error is between 24.050-24.250, we detect the results is the frequency of the gun has been partial to below 24.000. In that case, the detection range of the electronic dog on the K band is to do a lot of adjustment. At this point the journey of ZT-501's unique AFF intelligent filtering system will be able to play the effect.Adjusted to the K band range between 23.090 to 24.540, which also business advocacy said ultra-wideband. But the band width, the more false positives, this is a great disadvantage. Say KA, his values between 33.40 to 36, set by our electronic dog from 33.30 to 36.1 between. Thus, basically all the radar gun on the market, we can detect to. Journey the AFF intelligent filtering system based on long experience, directly on the number of false positives band masked and so as to achieve the effect of preventing interference.
