【摘要】：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。
[Abstract]:In order to solve the problem that the traditional (TOA) localization method with only measured pulse arrival time can not adapt to the radar signal of complex system, a new location algorithm based on TOA measurement is proposed. First, the pulse sample map of the emitter source is extracted by the master station. The secondary station uses the pulse sample map extracted by the main station to match and select the pulse sequence of the emitter received by the station, and the corresponding TOA data are transmitted back to the main station. Then the target location information field function is constructed by the TOA measurement of the main station and the location estimation of the emitter is realized by the grid search method. Simulation results show the effectiveness of the method.
