Abstract:

To satisfy the detection requirement of a multi-axis boresight for weapons systems, a novel detection method of large distance multi-axis boresight based on inertial reference is promoted and a detection system is designed. A two-dimensional galvanometer is used in the detection system to aim the direction of the measured axes. A gyroscope and photoelectric encoder are adopted to measure the vector coordinates of each measured axis in inertial space. The spatial angle between measured axes can be calculated by their vector coordinates, and then the boresight of the measured axes can be detected by their spatial angle. The mathematical model of multi-axis boresight detection is built, and error factors of the detection system are analyzed and calculated. Experimental analytical results show that the actual measurement error is 13.8^′′, which fully meets the requirements for multi-axis boresight detection in the wild.
