Description
technical field [0001] The invention relates to a digital gun sight system, in particular to an FPGA-based digital gun sight system. Background technique [0002] At present, when shooting, the gun sight needs to be adjusted manually according to various factors such as the distance of the shooting target, the local meteorological conditions, and the difference in gun bullets. Because the bullet is similar to a parabolic moving body when it is fired, it is affected by the combined effects of gravity and air resistance, and it flies out of a very complicated trajectory. Variables including primary, secondary and cubic variables are difficult to use mathematical formulas to complete servo control through a computer. Traditional human observation and manual adjustment of the scale are used to adjust the ballistic compensation of the gun sight. The accuracy is not high and it is not easy to achieve accuracy. Aim and shoot. Contents of the invention [0003] The technical pro...
