复杂电磁环境下多无源定位技术研究

Research of Multiple Passive Location Technology Under Complex Electromagnetic Environment

日益复杂的电磁环境条件下,无源定位技术以其独特的特点得到广泛应用。论文通过对多源传感器感知数据的关联处理,建立基于信号传播特性的测向数据关联关系,在交叉定位算法的基础上对各交叉点位的基本可信度进行分配,利用DS理论对感知数据进行融合,并在关联匹配中消除虚交点,从而得到较为精确的辐射源的位置。

Under the increasingly complex electromagnetic environmental conditions,passive location technology is widely used due to its unique characteristics.In this paper,through the correlation processing of multi-source sensor sensing data,the cor⁃relation relationship of the direction-finding data based on the signal propagation characteristics is established,and the basic credi⁃bility of each intersection location based on the cross-location algorithm is assigned.The DS(Dempster-Shafer)theory is utilized to the direction-finding data fusion and eliminate the false intersections in the correlation matching,so as to obtain a more accurate lo⁃cation of the radiation source.
