摘　　要：提出了一种基于拟Newton法的多非合作外辐射源的无源融合定位算法。该算法为多个外辐射源同时出现的情况下提供了一种融合算法,该算法可以直接根据定位参数迭代求出目标的运动状态。经过理论分析和仿真验证,在目标做近似匀速直线或者近似匀速曲线运动状态下,该算法收敛速度快,能提高定位精度,并能提高目标点迹的生存周期。In this paper,a new passive fusion location algorithm based on quasi-Newton method for multiple non-cooperative external emitters is proposed.The algorithm provides a fusion algorithm for the case of multiple external emitters appearing at the same time.By using the algorithm,the motion state of target can be directly caculated according to the positioning parameters iteration.After theoretical analysis and simulation verification,under the condition that the target moves in a straight line with approximately uniform velocity or in a curve with approximately uniform velocity,the algorithm has the advantages of fast convergence,and can improve the positioning accuracy and life cycle of the target trace.
