Source is set as corresponding S1, S2 ... Si, and records the latitude and longitude information in each region.
2. 1 direction finding data collection of position: mobile direction finding site is reached in the direction-measuring function of current location E1 activation system to multiple
Quick direction finding data to level detection thresholding and direction finding quality threshold are recorded.
3. the data preliminary screening of virtual target S1: obtain movement station current location E1 GPS information, calculate relative to
Virtual target S1's shows to angle value, and showing to angle value of surveying of movement station is compared with the value, is more than setting deviation
Data will be dropped, be finally according to number (as showing to degree matching value) by the U Degree U that shows for obtaining meeting virtual target S1
N1。
4. the data screening of other virtual targets: continue by showing of being measured in current location E1 to degree information respectively with remaining
S2 ... Si virtual target, which is shown to degree, to be screened, and also respectively obtain respective virtual target shows that degree matching value be N2 ... Ni.
5. the preliminary rejecting of virtual target: by SNmin virtual emission source corresponding to minimum value Nmin in N1 ... Ni from doubt
Like being weeded out in emission source set.
6. 2 direction finding data collection of position: mobile direction finding site presses predeterminable area, and shift position to E2 is again started up the survey of system
To function, multiple quick direction finding data for reaching level detection thresholding and direction finding quality threshold are recorded.
7. the screening again of virtual target data: in the manner aforesaid, obtaining the GPS letter of the current position E2 movement station again
Breath calculates showing to angle value relative to virtual target S1 ... Si-1, and actual measurement is shown to angle value and above-mentioned value and carries out matching ratio
Compared with obtaining S1 ..., Si-1's shows that degree matching value be respectively N1 ... Ni-1；
8. the rejecting again of virtual target: by SNmin2 virtual emission source corresponding to minimum value Nmin2 in N1 ... Ni-1
It is weeded out from doubtful emission source set.
9. the preliminary confirmation of emitting area: in remaining i-2 emission source, if can find twice test in show to
Degree matching value is the same area of maximum value, then can tentatively judge that emission source is located at the region.
10. emitting area continues to search: if can not find the region for meeting the condition or the region for meeting the condition not
, then monitoring station is continued to move to position E3, measure by aforementioned method and show that be will acquire shows to degree to degree screening by only one
Minimum value corresponding region is rejected in matching value.
11. emitting area is reaffirmed: if only a remaining region both can determine whether that the region had transmitting after rejecting
Source；Or repeatedly show that add up maximum sole zone and other leading regions more apparent to degree matching value in test at various locations
(specific threshold value can be preset) is emission source region.
12. the final confirmation of emitting area: continuing to move to monitoring station if requirements above is not satisfied to E4~EN
It sets, and carries out DATA REASONING and Screening Treatment, until requirement until meeting mobile monitoring station automatic positioning method step 11.
13. emitting area grid subdivision and positioning again:, can not if too big by the emitting area that the first run positions
Confirm the specific location of transmitting station, it is thin grid dividing can be re-started using this method again in the region that the first run confirms
Change, after passing through mostly wheel mesh refinement confirmation in this way, so that it may obtain sufficiently accurate position and be positioned for transmitting station.
It is in contrast to the prior art, the beneficial effects of the present invention are: region will be monitored using gridding cutting techniques
It is divided into multiple net regions to restrain step by step again, carries out quick interference source positioning searching work with all kinds of existing direction finding technologies
Make, City Building can be greatly reduced, and this works as the multipath effect caused with reflection, reduces the distortion rate of signal.
