Curved Distributed Shock Wave Projectile Positioning Device and Its Impact Point Positioning Method

Abstract

The invention relates to the field of accurate shooting automatic target-scoring equipment, and specifically relates to a curve distribution type shock wave bullet positioning apparatus and an impact point positioning method thereof. The apparatus comprises sensors and a support. The sensors comprise a middle sensor arranged in the middle part of the support, and side sensors symmetrically arranged at the two ends of the middle sensor. All the sensors are sequentially arranged along the circumference of the same circle, the circle center of the circle is located towards sensing ends of the sensors, and the circle center is located on a connecting line of the middle sensor and the center point of a target sheet. When the radius of the circle formed by the sensors is the minimum, the circle center is located at the center point of the target sheet. The invention also provides the impact point positioning method for the apparatus mentioned above. According to the method, a rectangular coordinate system is established by employing the middle sensor as the origin of coordinates, employing the horizontal direction as an X-axis, and employing the vertical direction as a Y-axis, and equations are solved through a trilateral relation theorem, so that positioning calculation steps are simplified, and the real reaction speed and target-scoring efficiency can be further improved.

The existing shock wave acoustic target equipment in China mostly adopts L-shaped or in-line sensor array distribution. ...

AI Technical Summary

Problems solved by technology

Due to the different waveforms, there will be errors in the judgment of the arrival time of the waveform during signal processing

In addition, the timer itself has errors, the longer it works, the longer the accumulated time error

Therefore, when the sensors are distributed horizontally, there will be a shock wave propagation distance difference at any point in the target area, especially at the 8-10 ring, where the distance difference is the largest, so the accuracy error of the horizontal distributed array is between 8-10 ring Larger, it cannot meet the requirements of frequent training shooters for the accuracy of shooting target reporting, because precision shooters hit more impact points in the 8-10 ring

Moreover, the current method of positioning the impact point of the horizontal inline sensor array mostly uses hyperbolic equations to solve, and the solution process is relatively complicated, which further increases the complexity of equipment calculations.
