Automatic Dependent Surveillance-Broadcast (ADS-B) is vulnerable to spoofing interference which will lead to the failure of Air Traffic Management (ATM) systems. This paper proposed an effective approach to detect and suppress the spoofing interference based on a cross-antenna array without estimating the direction of arrival (DOA) of the received signal. Firstly, the location of target is received by the antenna array. Then the azimuth and the elevation according to the antenna array are obtained based on the locations of target and the central element of array. Secondly, the signal from the estimated direction is suppressed by projecting the received signal onto the orthogonal complement space of estimated steering vector. Finally, the target is recognized as a real target or spoofing according to the spoofing decision algorithm. The simulation results show the effectiveness of the proposed algorithm.
