| 为了快速准确定位民航地面干扰源，提出了一种新的基于飞机散射信号的定位算法．首先，提出了新的初始参考点选取方法，并对此进行了理论分析和实验验证；然后，引入了相关熵和加权质心法，对现有算法进行了改进，同时进行了分析和实验验证．仿真实验结果表明，所提算法在保持计算量不变的前提下，显著地提升了基于飞机散射信号的民航地面干扰源定位精度，更具实用性． |
| 英文摘要: |
| A novel algorithm is proposed to locate the civil aviation ground interference source accurately and effectively via plane scattered signals. Firstly, a new method of arranging initial reference points is raised which is analyzed theoretically and testified experimentally. Secondly, correntropy and weighted centroid are introduced to optimize the existing locating algorithm. Both analyses and experiments are carried out. Simulation results show that the proposed algorithm improves the locating accuracy significantly and it has better practicality under equal amount of computations. |
