针对传统的仅测脉冲到达时间（TOA）定位方法不能适应复杂体制雷达信号的问题，提出了一种新的基于TOA测量的位置信息场定位算法。首先由主站自提取辐射源的脉冲样本图，副站利用主站自提取的脉冲样本图匹配分选出该站接收的辐射源脉冲列，并将其对应的TOA数据传回主站，而后由主站基于各站的TOA测量构造目标位置信息场函数，通过网格搜索法实现对辐射源位置的估计。仿真结果验证了该方法的有效性。

As the traditional location method based on TOA can’t adapt to complex radar signals,a new location method by position information field based on TOA is proposed in this paper. Firstly,the pulse pattern is self-extracted from the pulse train received by the master station,which is used by slave station to sort the emitter’s pulse data,and the TOA of the slave station’pulse data is transformed back to the master station. Then the master station constructs position information field function and obtains the emitter position estimate through grid searching method. Simulation results verify the effectiveness of the algorithm.
