Technical field

The invention relates to the technical field of photoelectric fire control, and in particular to a photoelectric fire control sight with intelligent ballistic correction.

Background technique

Optoelectronic fire control sights generally include direct sighting photoelectric fire control sights, curved sighting photoelectric fire control sights, and follow-up photoelectric fire control sights. Since individual weapon systems are generally used by individual soldiers or combat teams and have the characteristics of lightness and mobility, their fire control systems should be miniaturized, simple in structure, and easy to operate. Therefore, commonly used individual weapon systems are generally not equipped with open-loop, Follow-up photoelectric fire control sights are usually equipped with direct-aiming photoelectric fire-control sights, curved-aiming photoelectric fire-control sights or curved-aiming integrated photoelectric fire-control sights.

Conventional day and night photoelectric fire control sights are generally calculated based on environmental parameter variables and ballistic curves. Due to the comprehensive influence of factors such as the attitude and shooting angle of the weapon system when shooting, the shooter often needs to pay attention to the shooting attitude, shooting estimate correction, etc. before shooting. It is conducive to the rapidly changing battlefield and may delay fighter opportunities. Therefore, day and night photoelectric fire control sights should solve practical problems in weapon system applications to meet the requirements for intelligent adaptation of photoelectric fire control sights.
