摘要
Abstract
We investigated the optimal intersection problem of a direction-finding cross-location system composed of 1D and 2D passive sensors.Utilizing closed-form solutions for localization accuracy,extremum analysis,and geometric in-tersection analysis,we identified the global optimal intersection point and explored the spatial distribution characteristics of optimal intersection positions,as well as their influencing factors and underlying principles.The study reveals that the glob-al optimal intersection point lies in the horizontal plane of the baseline(or 2D sensor).The optimal intersection locations are jointly determined by the geometric intersection characteristics and the distance diffusion effect of measurement errors,dis-tributed around an arc on the horizontal plane with the midpoint of the baseline as the center and the baseline length as the diameter,collapsing towards the baseline.Variations in sensor positions do not affect the relative position of the optimal in-tersection location to the baseline;once the variance ratio of the baseline and angular measurement errors is established,the optimal intersection location is determined.Furthermore,case analysis suggests that the optimal intersection area converges towards sensor with larger angular measurement errors.In practical engineering applications,the optimal intersection area holds greater utility than the optimal intersection point;matching the optimal intersection locations with target detection re-sults or estimated positions can effectively enhance the system's positioning performance.关键词
