A scheme for deception jamming detection based on beam scanning is proposed in this letter. This scheme detects the authenticity of the corresponding signal by forming a null in the direction of each visible satellite in turn. At the same time, the null direction is adjusted based on the attitude angle measured by the inertial unit to support the applicability of the scheme in scenarios where the attitude of the array changes continuously. Then, from an engineering point of view, an equalization scheme for arrays and radio frequency (RF) channels is proposed to improve the accuracy of the null direction. Finally, the effectiveness of the proposed scheme is verified by simulation.
