This Thesis focuses on 300-meter shooting training with snipers. Currently, there are devices available to estimate the location of a projectile’s impact on a shooting target, thus optimizing time in free training sessions. However, these devices do not possess optimal precision and accuracy, due to their design being based on ideal modeling, using a constant value of 343 m/s for the speed of sound, which is inaccurate. According to studies, the speed of sound mainly depends on environmental variables such as temperature and relative humidity. This Thesis modeling of a projectile impact detection system was carried out based on data analysis, using RCAPE (acronym in Spanish) modeling methods, backfitting, and neural networks. Furthermore, the system under study was modeled using triangulation modeling to obtain a model based on ideal conditions. To obtain experimental data and perform experimental validation in the laboratory, a prototype equipped with sound, temperature, relative humidity sensors, and an XY positioner was constructed, which moves a sound emitter at different points of the shooting target to emulate projectile impacts under different environmental conditions. When performing modeling with the four methods, it was observed that the neural network method made a more accurate estimation of the emulated projectile impact location, with an estimation error of 2 mm. The results of the modeling by RCAPE, backfitting, and triangulation showed estimation errors of 20 mm, 32 mm, and 27 mm, respectively. The results show that projectile impact estimation can be improved using computational modeling methods.
