A technology for deviation measurement of artillery Impact point is discussed with reference to signal processing, ballistic trajectory calculating and software designing. The principle and algorithm are used to shorten the time for calculating the impact point and calibration. Equipped with high speed computer and DSP module, the instrument is controlled with close-loop and drivers inside. Thus, automatic shooting calculation is implemented and the accuracy is improved. The function block of image and graphic signal storage is also added for playback and analysis. The technology is further applied to air and off-shore targets in all weathers meeting requirements of artillery shooting and its calibration.
