中文摘要：

通常雷达数据处理在航迹维持阶段,仅存在目标与量测的数据关联问题。单频网外辐射源雷达多个发射站同频同时发射相同的波形,因此还存在量测与发射站的关联问题。该文针对单频网外辐射源雷达目标跟踪的航迹维持阶段,重点研究了单频网下发射站—目标—量测三者的数据关联问题,通过将量测与发射站的关联融入常规的目标与量测的关联过程,使得发射站、目标和量测的多维关联问题转化为二维分配问题,得到了一种适用于单频网的航迹维持新方法,仿真和实测数据验证了该方法的有效性。

英文摘要：

There is only target-to-measurement association during track maintenance in conventional radar data processing.However,there exists the measurement-to-transmitter association in single frequency network（SFN）based passive radar where all illuminators transmit the same signal at the same frequency simultaneously.The problem of target track maintenance in SFN based passive radar is examined.The primary objective is to solve the data association problem of transmitter-target-measurement in SFN.Specifically,the association of measurement-to-transmitter is integrated into the procedure of conventional association between the target and the measurement.Therefore,a method of track maintenance is obtained by transforming the multi-dimensional assignment problem into a 2-dimensional assignment problem.In addition,the validity of the method is demonstrated by both simulations and field experimental data.
