摘要
为了克服无线电网格化建设中多站无源时差定位技术人为选站方案效率低、准确度不高等缺陷,设计了一种用于多站TDOA定位的自动选站优化算法。根据不同监测站接收的TDOA信号数据及各监测站的位置信息,考虑TDOA定位布站准则及人为经验,由计算机依据设定算法自动选择最优的3个监测站节点进行TDOA定位。选取兰州中川机场网格化实际监测TDOA数据进行算法验证,结果表明提出的算法能够较好、快速、准确地选择最优3站参与TDOA定位,为无线电监测及网格化布站方案,提供一种有效的信号定位自动选站优化方案,且算法具有易于代码移植及工程实现的优点。
In order to overcome the defects such as low efficiency and low accuracy of multi-station TDOA location technology in radio grid construction by artificial mode,an automatic station optimization algorithm for multi-station TDOA positioning is designed.According to the TDOA signal data and the location information received by different monitoring stations,and considering the criteria and man-made experience of TDOA positioning station,the optimal three monitoring station nodes are automatically selected by the computer according to the setting algorithm.Furthermore,the algorithm is validated through real TDOA data of Lanzhou Zhongchuan Airport Radio Grid.The results show that the proposed algorithm can select optimally,fast and accurately the optimal three stations for TDOA positioning,which provides an effective signal positioning automatic station optimization scheme for the radio monitoring and grid layout scheme.Otherwise,the algorithm has such advantages as easy code porting and engineering realization,and it has good practical significance.
