| Abstract: | In this paper,configurations of 4-station short-baseline systems are investigated in order to minimize the transverse localization error of a directed moving target.Starting from the localization equation followed by a careful quantitative analysis of the involved parameters in the resulting error estimation equation,two coplanar 4-station short- baseline arrays are proposed.It is shown that high-accuracy transverse measuring for moving target can be realized by adding only one more redundant measuring station.Moreover,the derived configurations of the base station are conformed to those deducted from the localization precision analysis results. |
