Abstract

On the ground of research of dynamic laser fixed-distance detection system carry on board a protective, this paper discusses and analyzes the factors that affect the ranging accuracy of the system. On the basis of correlation detection theory and according to the system requirements on ranging accuracy and sensitivity, the effects of the values of main parameters, such as lasers' cycle, pulse width and ascending fringe, on ranging accuracy are described; a comprehensive analysis is given on the power requirements due to the reflectance of the target, ranging distance length, the sensitivity of detectors, and the coupling efficiency of the relative coupling devices.
