The basic parameters of the combat training and weapon practicing are the determination of the accuracy and precision. The automatic systems for acquiring of the hit pattern are very expensive and inaccessible. Modern automatic systems are designed as nonmaterial target system for accurate spatial positioning of the projectile trajectory in one or more planes. In the paper will be described the design of the non-material high-resolution target acquisition system developed on the optoelectronics IR (infra-red) sensors. The frame of the multiple IR sensors coupled with the microcomputer platform is the optical frame. The complete target acquisition system is consisted of the two frames for positioning in vertical and horizontal direction. Additionally, in the target system is incorporated the algorithm for the determination of the appropriate statistical values from the group of shots, as accuracy and precision parameters. The assembly hardware components are commercially accessible. The designed algorithm is applied through simple software code. The main aim of the developed target system is for the measurement of the small arms shooting. The presented target system is open for enhancement and can be used for different weapon system.

The accurate values of the initial velocity of bullets are significant for the quality and precision of small arms. The application of the simple measurement methods, during the tests of the weapon and ammunition, enables the determination of the velocity values from the group of shoots. The accuracy of bullet trajectory, appropriate trajectory correction parameters and terminal ballistics parameters are depended of the quality of initial conditions as initial velocity. The ballistic pendulum, as simple and old-design device, enhanced with optoelectronic encoder sensor and computer acquisition system, can be one of the good start-up device platform for measurement of velocity and observation of the terminal ballistics effects. The function principle of the considered device is based on the energy conservation. Initial data are mass of bullet, mass and dimension of pendulum, and result is velocity, according to the values of time and angle of pendulum. The output signals of measured angle in time are captured, and as required values for calculation the velocity on the microprocessor platform, for each shoot in the test group. The microprocessor platform saves measured and calculated values in memory and generates statistic report of results. The presented method can improve weapon and ammunition tests, by decreasing the time of measurement acquisition and increasing the quality and speed of results without errors. The method and system is simple and low-cost, and enables the design of small arms ammunition database of testing results.
