Model studies on the accurate positioning of rocket debris

In this paper, four sets of evenly distributed characteristic devices are selected according to the least squares method to calculate the position and time of the arrival of the explosive sound and the position and time of the booster, and use the multi-source location measurement method to measure the position of the sound source. After obtaining the optimal model, the results are verified by the objective function method; the straight-line distance between each monitoring device and each fragment is obtained by using the Euclidean formula. Since the random error of the device recording time is 0.5s, the fragment propagation time to the device is calculated using the time error model formula based on the linear distance. Finally, the relationship between the falling position of multiple rocket debris and the location of vibration wave monitoring equipment, the arrival time of the number of rocket debris and the number of vibration wave monitoring equipment are studied.
