[0052] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] See also Figure 1 This embodiment provides an electromagnetic pulse positioning method, comprising the following steps:

[0054] Step 101: Determine all monitoring points that have received electromagnetic pulse events within a preset period before the current moment as initial monitoring points.

[0055] It should be noted that the purpose of this step is to collect data from all monitoring points that received electromagnetic pulse (EMP) signals within a specific time period to provide basic data for subsequent screening and positioning.

[0056] Step 102: According to the theoretical reception time difference of each initial monitoring point for the same electromagnetic pulse event, all the initial monitoring points are determined as a plurality of groups of target monitoring points according to different electromagnetic pulse events.

[0057] It should be noted that this step uses time differences to filter out monitoring points that truly belong to the same EMP event, avoid interference from irrelevant signals, and improve positioning accuracy. The screening process is to calculate the theoretical time difference of each initial monitoring point receiving the EMP signal. Compare the time differences between the monitoring points. If the difference exceeds a certain threshold, it is considered that the signals received by these monitoring points do not belong to the same EMP event. Group the monitoring points with smaller time differences into a group to form a group of target monitoring points corresponding to a certain EMP event.

[0058] Step 103: For each group of target monitoring points, based on the position of each target monitoring point and the difference in the start receiving time of the electromagnetic pulse event at different target monitoring points, the electromagnetic pulse event is located.

[0059] It should be noted that this step calculates the precise location of the EMP event through the time difference and geographical location information of multiple monitoring points. The method for calculating the location can use multi-lateration or multi-point positioning algorithms, such as TDOA (Time Difference of Arrival) method.

[0060] This embodiment provides an electromagnetic pulse positioning method, which calculates the specific location of the EMP event based on the position and time difference of the effective monitoring points after screening. This method effectively reduces the error introduced by irrelevant signals and improves the accuracy and reliability of positioning. Through the time difference data of multiple monitoring points, the EMP event can be accurately positioned.

[0061] In an exemplary embodiment, step 102 includes:

[0062] Step 102-1: Determine any initial monitoring point as the current initial point.

[0063] Step 102 - 2 : Determine any initial monitoring point other than the current initial point as the current comparison initial point.

[0064] Step 102 - 3 : Determine the difference between the start receiving time corresponding to the current comparison initial point and the start receiving time corresponding to the current initial point as the current initial time difference.

[0065] Step 102-4: Determine whether the current initial time difference reaches the theoretical maximum transmission time difference, and obtain a first determination result. If the first determination result is yes, execute step 102-5; if the first determination result is no, execute step 102-6.

[0066] Step 102-5: Delete the current comparison initial point and return to step 102-2.

[0067] Step 102-6: Return to step 102-2 until all initial monitoring points except the current initial point are traversed.

[0068] Step 102-7: Update the current initial point and return to 102-2 until all initial monitoring points are traversed to obtain multiple target monitoring points.

[0069] In this embodiment, interference signals are eliminated through time correlation and waveform correlation to complete the event identity determination: determine whether the time difference between the signals arriving at different sensors exceeds the theoretical maximum transmission time difference, and determine the signals exceeding the theoretical expectation as interference and eliminate them; if the time difference conforms to the theoretical expected waveform, further cross-correlation analysis is performed, and when the waveform correlation coefficient is less than the set threshold, it is determined as interference and eliminated; all waveforms of the same event are screened out to complete the event identity determination.

[0070] In an exemplary embodiment, step 103 includes:

[0071] Step 103-1: Determine any target monitoring point as the current reference point.

[0072] Step 103 - 2 : Determine any target monitoring point other than the current reference point as the current comparison target point.

[0073] Step 103 - 3 : According to the position of the current comparison target point and the position of the current reference point, determine the distance from the current comparison target point to the current reference point as the current reference distance.

[0074] Step 103 - 4 : Determine the difference between the start receiving time corresponding to the current comparison target point and the start receiving time corresponding to the current reference point as the current reference time difference.

[0075] Step 103 - 5 : Based on the current reference distance, the current reference time difference and the speed of light, determine the pending distance from the electromagnetic pulse event corresponding to the current comparison target point to the current reference point.

[0076] Step 103-6: Update the current comparison target point, and return to step 103-3 until all target monitoring points other than the current reference point are traversed to obtain the pending distances from the electromagnetic pulse events corresponding to all comparison target points to the current reference point.

[0077] Step 103 - 7 : Determine the average value of the undetermined distances from the electromagnetic pulse events corresponding to all comparison target points to the current reference point, which is the reference distance from the electromagnetic pulse event to the current reference point.

[0078] Step 103 - 8 : Draw a circle with the current reference point as the center and the reference distance from the electromagnetic pulse event to the current reference point as the radius to obtain the electromagnetic pulse event positioning circle corresponding to the current reference point.

[0079] Step 103-9: Update the current reference point and return to step 103-2 until all target monitoring points are traversed to obtain the electromagnetic pulse event positioning circle corresponding to each target monitoring point.

[0080] Step 103 - 10: Locate the electromagnetic pulse event based on the electromagnetic pulse event positioning circle corresponding to each target monitoring point.

[0081] In a further embodiment, step 103-10 includes:

[0082] Step 103-10-1: Obtain the positioning intersection point. The number of electromagnetic pulse event positioning circles passing through the positioning intersection point is at least 3.

[0083] Step 103-10-2: When the number of the positioning intersection points is equal to 1, the positioning intersection point is determined to be the electromagnetic pulse event position.

[0084] Step 103-10-3: When the number of the positioning intersection points is greater than 1, determine the average of all the positioning intersection points as the electromagnetic pulse event position.

[0085] Step 103-10-4: When the number of positioning intersections is equal to 0, obtain the reference intersection. The number of electromagnetic pulse event positioning circles passing through the reference intersection is 2.

[0086] Step 103-10-5: Determine the average of all reference intersection points as the electromagnetic pulse event location.

[0087] In a further embodiment, the calculation of the distance to be determined in step 103-5 is as follows:

[0088]

[0089] In the formula, is the undetermined distance from the electromagnetic pulse event corresponding to the current comparison target point to the current reference point, is the current reference distance, is the current reference time difference, The speed of light.
