RESEARCH ON DETECTION SYSTEM OF LARGE DISTANCE MULTI-AXES BORESIGHT

摘要

To satisfy the detection requirement of multi-axes boresight for weapon system, a novel detection method of large distance multi-axes 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 measured axis. 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 measured axes can be detected by their spatial angle. The mathematical model of multi-axes boresight detection is built and error factors of detection system are analyzed and calculated. Experimental analytical results show that the actual measurement error is 13.8" which meets the requirements of multi-axes boresight detection in wild completely.
