Embodiment Construction

[0056] The mast inclination correction device designed by the present invention includes an angle measurement unit and a computer board assembly. The angle measurement unit is a set of tilt sensor components, including the upper tilt sensor C2 and the lower tilt sensor C1, which are respectively installed on the reference plane of the sighting instrument and the base plane of the bomb rack platform. The upper tilt sensor C2 can measure the rotation angle between the scope and the earth coordinate system, and the lower tilt sensor C1 can measure the rotation angle between the missile carrier platform and the earth coordinate system. The computer board includes: an interface part and a data processing module of the bomb rack inclination sensor. The interface part of the bomb rack tilt sensor includes an initialization unit, a data fetching instruction input unit, and a data input unit. The initialization unit is the initialization of the bomb rack tilt sensor RS232; the data fe...

Abstract

The invention provides a vehicle-mounted mast inclining amount correction method. Two high-precision inclined sensors are mounted on mounting basic surfaces of the bottom and top of a mast respectively, wherein the inclined sensor C1 is mounted on a vehicle body basic surface, and the inclined sensor C2 is mounted on an observing and aiming instrument mounting basic surface; the mounting directions of the C1 and C2 are strictly the same; inclined values in y and x directions, which are output by the inclined sensor C1 and the inclined sensor C2, are compared; an axis angle of an observing and aiming instrument, and lateral inclined values of the inclined sensor C1 and the inclined sensor C2 are combined and converted to the vehicle body basic surface; data is input into a computer control panel to be subjected to operation including polar coordinate conversion and the like, and participates in system angle measurement output correction, so that the elevation error caused by the mast is not more than 0.1mil; and a finally-calculated result is used as the standard of a missile frame of a guided missile to guide the missile frame of the guided missile to move to an appointed position, so that an appointed target is attacked.

Description

technical field [0001] The invention relates to the technical field of photoelectric reconnaissance, and mainly relates to a correction method, in particular to a method for correcting the inclination of a vehicle-mounted mast, which is used to eliminate the inclination of the photoelectric mast. Background technique [0002] The vehicle-mounted or ground-based photoelectric reconnaissance system is widely used in the reconnaissance field because of its advantages of high precision and strong anti-interference ability. These reconnaissance systems often integrate a variety of optical and electrical sensors such as visible light, infrared, laser, and radar, and can realize functions such as reconnaissance and high-precision positioning of ground targets. In practical applications, due to factors such as occlusion by ground objects and the curvature of the earth, the observation distance of traditional reconnaissance systems is greatly limited, and often fails to reach the ide...
