| 摘 要： | 在海战场环境中,目标载辐射源(TS)常常辐射多种信号以实现通信、探测和导航等功能。然而,上述信号没有被传统的被动相干定位系统(PCLS)充分利用。文中提出了一种联合TS和外辐射源(IO)量测信息的无源跟踪模型,以TS提供的多普勒频差和IO 提供的到达时间(TOA)为目标联合观测量,提高了目标状态的估计精度。最后,以均方根误差(RMSE)为指标证明了模型的先进性。

| Abstract: | In the naval battlefield environment, various signals will be radiated into space by the target source (TS) for communicating, detecting or navigating. However, these signals are not efficiently used by conventional passive coherent location system (PCLS). A passive tracking method combined with the TS and the illuminator of opportunity (IO) observations is proposed, which utilizes both Doppler difference produced by TS and time of arrival (TOA) created by IO as joint target measurements. It improves the estimation accuracy of the target state. Finally, superiority of the proposed model is proved with the root mean squares error (RMSE) as the indicator. |
