| 摘要: |
| 多站电子侦察系统中，两个观测站接收到的脉冲信号到达时间差可以用于分选和定位。针对复杂信号脉间信息关联性弱，不能对脉冲数极少的信号进行分选的问题，提出一种多站时差与多参数联合分选定位新方法。该方法利用时差窗先验信息，将主站和所有副站脉冲同时进行多站时差和多参数联合预分选，并将预分选结果按位置进行融合，得到最终分选和定位结果，能对脉冲数极少的信号进行分选定位，甚至可实现单个脉冲的分选定位。仿真结果表明了该方法的有效性。 |

| Abstract: |
| In multi-station electronic reconnaissance system, TDOA (Time Difference Of Arrival) of the pulse signal received by two stations can be used for signal sorting and positioning. A novel method for joint sorting and location based on TDOA and multi parameter of multi-station was proposed to deal with the problem of being unable to sort the signals with very few pulses caused by weak correlation between pulse information of complex signals in order to obtain final sorting and location results, the pulses of all stations were presorted by the presented method with TDOA window information and the presorting results were integrated according to targets’ positions. Simulation results show that the proposed method is applicable and effective, which can implement the pulse signal sorting and positioning with very few pulses and even a single pulse sorting and positioning. |
