Description
Technical field
The invention belongs to field of photoelectric technology, relate generally to a kind of vehicular photoelectric tracker, particularly relate to a kind of pitching frame structural constituent of vehicular photoelectric tracker.
Background technology
Along with the air strike development of platform and widely using of precision guided weapon; constantly increase from aerial threat; in order to complete the challenge of air-defense anti-missile; the Close-in Anti-Missile Weapon Systems such as " photovoltaic strip big gun " or " photoelectricity extension bullet " as actv. interception means be widely applied to vehicular platform, hip-based platform or other need protection critical facility, building near, to improve the survival rate of self.
The essential structure form of optronic tracker mainly comprises two great institutions and azimuth mechanism and luffing mechanism, the status of pitching frame assembly in whole optronic tracker is just as " human eye ", to obtain the kinematic parameter of attacking target in the air, pass to fire control computer in real time, guiding cannon or guided missile destroy attacks target.
Along with the development of science and technology and the demand of device miniaturization, various optical pickocff is all in the design carrying out miniaturization and integration, for range finder using laser, range finder using laser is in the past primarily of laser main frame and electronic box two parts composition, high-power, the circuit card of high hear rate is all arranged on independently in electronic box, only laser main frame is arranged on pitching frame assembly, and rotate around pitch axis with pitching frame assembly, electronic box is independently installed in addition, be connected by cable between it with laser main frame and transmit various control signal, outside frame in common version such as national defence patent ZL200310102044.7 " being applicable to two frame assemblies of carrier-borne optronic tracker ", its version be one by front spherical shell, the approximate spheres that spherical shell keel and rear spherical shell three part are formed, before, rear spherical shell connects firmly on spherical shell keel, the spherical shell keel left and right sides connects firmly with Y-axis system respectively.Approximate spheres is built with TV detector, thermal infrared imager, laser main frame, and electronic laser case is independently installed; Another is also design like this by the carrier-borne optronic tracker of H/ZGJ-1 type of total 717 Research Institute of ship in China, and such version is the demand that cannot realize sensor independence subdivision.Now because new pattern laser range finder takes integration and Miniaturization Design, original laser main frame and electronic unit are united two into one, if TV detector, thermal infrared imager, integrated laser range finder are arranged in an airtight space by the mounting means also mentioned by above-mentioned patent, the heat that so integrated laser range finder produces just cannot distribute by actv., the temperature in seal hatch is directly caused sharply to raise, not only self cannot normally work, and other optical pickocff can be had influence on normally work, increase trouble point.
