1. a multistation lightning very high frequency(VHF) radiation source 3-D positioning method is characterized in that, specifically comprises:

  • Step 1, at least three single stations of setting websites, each single station website constitutes the two antenna array of vertical baseline, reaches the phase differential relation of single station website by measurement lightning ELECTROMAGNETIC RADIATION SIGNATURE Or the mistiming Calculate the lightning radiation source elevation angle;

    Wherein;

    f is the frequency of lightning ELECTROMAGNETIC RADIATION SIGNATURE, and c is the light velocity, and d is two base length between the antenna, and θ

    is the lightning radiation source elevation angle;

    Step 2, record lightning electromagnetic signal arrive the temporal information at each single station;

    After step 3, the elevation angle of at every turn being triggered and the temporal information, match by temporal information, if the list station more than three or three measures the elevation angle of same lightning radiation source, then obtain suitable fixed or overdetermined equation group, calculate the three-dimensional location coordinates of radiation source.
