Embodiment approach

[0084] 1) Level the aircraft, that is, adjust the horizontal and longitudinal directions of the aircraft. The method is: arrange two measuring points symmetrically on the left and right wings of the aircraft. Two measurement points are arranged in the direction of the aircraft fuselage, and the height difference between the two points is within 0.5mm to achieve longitudinal leveling. Secondly, the measurement coordinate system of the laser tracker is the same as the assembly coordinate system of the aircraft general assembly station. Here, the laser tracking The measurement coordinate system of the laser tracker refers to the spatial coordinate system automatically established by default after the laser tracker is turned on, while the assembly coordinate system of the aircraft general assembly site refers to the spatial coordinate system defined by the designer according to the layout of the aircraft general assembly on site. The method of the latter is: by measuring several pu...

Abstract

The invention discloses a digitized radar boresight method applied to plane general assembly, comprising the following steps of: (1) leveling a plane, unifying a measuring coordinate system of a laser tracker with an assembly coordinate system of a plane general assembly station and centering a water bubble on a radar boresight device; (2) measuring a No. 2 point and a No. 12 point by utilizing the laser tracker and automatically constructing a symmetric axis of the plane by a computer; (3) starting a measuring program and finishing the measurement of a target on the radar boresight device by adopting a manual or automatic measuring mode; (4) calculating and displaying the deviations of a radar-mounting direction relative to the construction plane and the symmetric axis of the plane through patterns and finishing radar boresight if satisfying the requirement or else continuing the radar boresight; and (5) manually adjusting the radar direction according to the prompts of the computer and repeating the steps (3) and (4) until reaching the boresight requirement. The invention effectively improves the boresight precision and the efficiency, lessens the reliance of boresight operation on the size of a working field space, and improves the automated and integrated level of plane general assembly.

Description

technical field [0001] The invention relates to a target calibration method, in particular to a radar digital target calibration method applied to aircraft general assembly. Background technique [0002] Radar is an important part of the air weapon system, and its technical level determines the combat performance of military aircraft. It is mainly used to control (including guidance) airborne weapons, implement air security, investigation, ensure accurate navigation and flight safety, etc., and is an important technical equipment of modern military aircraft. Ensuring the accurate installation of the radar is the premise and basis for its normal operation. Over the years, the radar target calibration method in our country still follows the traditional optical target calibration method, the degree of automation is low, the reliability of the measurement data is poor, and the space occupied by the work site is large, which seriously inhibits the improvement of target calibrati...
