Acoustics-Based Model for Spotting Exactly Points of Impact of Bombs/Shells

An acoustics-based mathematic model is developed to detect exactly the points of impact of bombs/shells. Receiving detonation sound wave signal by acoustics sensors to get the relative time data of sonic transmission and taking account of the effects of background noise, temperature, humidity and wind speed/direction on detonation sound wave. The model can be used to calculate the exact position of a point of impact rapidly. Then, the result is sent to the command control post automatically as reference for calibration to modify firing data. The whole service practice firing shooting can thus be evaluated scientifically and precisely. As proved by actual spotting verification, the model is regarded as exact and effective in improving the efficiency of military drill, with expenses reduced greatly.
