Embodiment 1

[0036] The detection of the explosion position of the ground penetrating bomb is of great significance to the research and performance evaluation of the ground penetrating bomb. The ground penetrating bomb is a kind of underground guided bomb, and its trajectory is in the formation. Therefore, compared with space or ground target positioning technology, it is much more difficult to estimate the underground trajectory of the ground penetrating projectile, especially the detection and positioning of the explosion position. In order to carry out research in this area, the present invention provides a system and method for locating the explosion position of an earth-penetrating projectile in a shooting range.

[0037] see figure 1 , the present invention is an explosion position positioning system for ground penetrating projectiles in a shooting range, which includes an explosion source, a synchronous geophone, an electronic computer and a wireless transmitter; Take the origin of ...

Embodiment 2

[0042] The present invention is a shooting range ground-penetrating bomb explosion position positioning system, and also a shooting range ground-penetrating bomb explosion position positioning method. The positioning method is realized on the above-mentioned shooting range ground-penetrating bomb explosion position positioning system. See image 3 , the positioning of the explosion position of the ground penetrating bomb specifically includes:

[0043] The first step is to choose a point on the shooting range as the origin of the space Cartesian coordinate system, take the two directions orthogonal to the origin on the surface as the X-axis and Y-axis of the coordinate system, and take the vertical downward of the origin as the Z of the coordinate system Axis, bury a synchronous geophone at the origin, bury a synchronous geophone at the distance D meters between the X, Y, and Z axes and the origin, and bury a synchronous geophone at a distance from the origin to D meters of the...

Embodiment 3

[0070] The location system and method for the explosion position of the ground penetrating projectile in the shooting range are the same as in Embodiment 1-2, and the present invention is further described in conjunction with the simulation results:

[0071] Layout plan: see figure 2 , taking a corner of the 100-meter-square shooting range as the coordinate origin, and taking north, east, and down as the positive directions of the X, Y, and Z coordinate axes in turn. The scope of the shooting range experiment area is set to 100m*100m*100m. A synchronous geophone is buried at a distance of 100 meters from the origin on the X, Y, and Z axes, and an explosion source is buried on the Z axis at a distance of 98 meters from the origin. The position of explosion source 0 is recorded as (x 0 ,y 0 ,z 0 )=(0,0,-98), record the position of the buried synchronous geophone at the origin as (x[1],y[1],z[1])=(0,0,0), X-axis The position of the buried synchronous geophone is recorded as...

Abstract

The invention provides a system and a method for positioning explosion site of a penetrating bomb in a shooting range. The method comprises the following steps: selecting an orthogonal three-dimensional space; embedding synchronous seismic detectors at an original point and some points on X, Y and Z axes with equal distances of D meters from the original point; embedding an explosive source on the Z axis at a distance slightly smaller than D meters; sending a synchronizing signal to trigger the explosive source by an electronic computer; starting the synchronous seismic detectors; after one experimental period, sending a sleeping signal then to lock the synchronous seismic detectors; and interacting data in the detectors with data in the electronic computer. In the positioning method, the time information is extracted through contrastive analysis on wave crest sequences before and after the explosive experiment of the penetrating bomb. By utilizing time information, average propagation velocity of the shock wave and related position information, a model is constructed, model crossing points are solved, and the explosion site of the penetrating bomb is calculated. The system and the method overcome the disadvantages in the prior that the positioning accuracy is low and the environment is easily polluted, have the advantages of high positioning accuracy, simple implementation, high anti-interference performance, simple modeling and less calculation, and can be used for determining the explosion site of the penetrating bomb in the shooting range.
