| 摘 要： | 在多无人机（UAV）协同定位地面固定辐射源的应用环境中，为了提高多机基于时差的定位精度，提出一种改进的基于约束总体最小二乘（CTLS）的时差定位方法和一种基于结构总体最小范数（STLN）的时差定位方法．证明了这两种方法具有相同的定位精度，但STLN方法的计算性能优于改进的CTLS方法．仿真结果表明，所提出的方法具有较高的定位精度，受观测点定位误差影响更小．

| Abstract: | When a formation of unmanned aerial vehicles(UAV) is used to localize a fixed target on the ground using time difference of arrival,in order to improve the localization accuracy,an improved method based on the constrained total least squares(CTLS) and a method based on the structured total least norm(STLN) are proposed.Both methods are proved to have the same positioning accuracy,but the computational performance of STLN method is superior to CTLS method.Simulation results show that the proposed methods hav... |
