The embodiment of the present invention is illustrated below in conjunction with Figure of description, it should be understood that implementation described herein
Example is merely to illustrate and explain the present invention, and is not intended to restrict the invention.And in the absence of conflict, the reality in the present invention
The feature for applying example and embodiment can be combined with each other.
The embodiment of the invention provides a kind of Intermodulation Interference localization methods, as shown in Figure 1, being the implementation process of this method
Figure, specifically include the following steps:
Step 11, by frequency sweep data, determine that be disturbed region is disturbed information；Wherein, it includes: dry for being disturbed information
The frequency and level intensity of signal are disturbed, and is disturbed the location information in region.
Wherein, the location information for being disturbed region is longitude and latitude positional information.
Step 12, according to information and pre-set base station transmitting power is disturbed, determine that there may be Intermodulation Interferences
Regional scope.
Specifically, the step 12 can be, but not limited to realize as follows:
According to the frequency of interference signal and level intensity and pre-set base station transmitting power, interference signal is determined
Propagation distance；
According to the location information for being disturbed region, the central point for being disturbed region is determined；
Be disturbed the central point in region as the center of circle using this, using the propagation distance of interference signal as radius, determine there may be

It is determined using pre-set Intermodulation Interference formula.
Intermodulation is divided into the intermodulation of 3 ranks, 5 ranks, 7 ranks and higher order number, due to higher-order number intermodulation influence relatively
It is small, therefore it is only concerned the intermodulation of 3 ranks, 5 ranks and 7 ranks under normal circumstances.
3 most general rank Intermodulation Interference formula: F (IM3)=2*F1-F2；
Wherein, F1 and F2 be base station frequency group information in include frequency point.
But when the frequency point for including in the frequency group information of base station is more, only 2 frequency points can not generate intermodulation
Interference, multiple frequency point interactions can also generate Intermodulation Interference, and fall in frequency range, and it is mutual to be thus derived another 3 rank
Cadre enrolled among workers disturbs formula: F (IM3)=F1+F2-F3.
5 rank Intermodulation Interference formula: F (IM5)=3*F1-2*F2；
Likewise, can also derive 5 a number of other rank Intermodulation Interference formula:
Such as: F (IM5)=2*F1+F2-2*F3 or 2*F1+f2-f3-f4.
7 rank Intermodulation Interference formula: F (IM7)=4*F1-3*F2；
Likewise, can also derive 7 a number of other rank Intermodulation Interference formula:
F (IM7)=3*F1+F2-3*F2 or 2*F1+2*F2-2*F3-F4 or 2*F1+F2+F3-2*F4-F5.
