| 摘要: |
| 单频网外辐射源雷达存在测量-发射站关联模糊的问题，在进行目标定位时必须考虑测量-发射站关联解模糊问题。基于此，建立了单频网外辐射源雷达系统测量-发射站关联模型，推导了三维TOA定位方法以及估计目标高度的二维TOA定位方法原理，给出了相应算法的GDOP定位精度分析，并通过一个三发单收的外辐射源定位模型仿真验证，分析了不同算法对定位精度以及对测量-发射站关联的影响。结果表明，采用估计目标高度的二维TOA定位方法能够提高单频网外辐射源雷达测量-发射站关联概率。 |

| Abstract: |
| In single frequency network (SFN) based passive radar systems，the measurement-transmitter association problem must be taken into consideration to choose the targeting methods. In this article，we establish the targeting model of 3D TOA location method and 2D TOA location method for SFN based passive radar systems and analyze the influence of the height bias on the location accuracy and the measure-transmitter association. The simulation results show that the 2D TOA location algorithm can promote the measurement-transmitter association probability. |
| Key words: single frequency network(SFN) passive radar measurement-transmitter association location accuracy |
