Abstract: The latest domestic experimental research of UHF passive radar on moving platform based on digital television signal using the newly-developed multi-channel passive radar system is conducted.Firstly, the receiving signal model in the single frequency network (SFN) is established.And then a clutter suppression method combined the improved extensive can cellation algorithmbatchs (ECA-B) and space-time adaptive processing (STAP) is discussed in details.Finally, the experimental progress is highlighted, involving system introduction, illustration and analysis of typical results.The results of simulation and measured data processing prove the validity of the model and the superiority of the clutter suppressing method, forming the theoretical and experimental basis for the further development of this detecting technology.
