Background/Objectives: This paper describes an analysis of the effectiveness for an anti-ARM technique to protect a radar system. Methods/Statistical analysis: We investigate the optimum deployment of decoy antennas which are widely using for anti-ARM and the electromagnetic field at the ARM receiver. The simulation results regarding the performance of decoys based on the signal's Angle of Arrival (AoA) in 3D geometry. To verify the effect of decoy antennas, we analyze the field intensity and phase at the receiver and develop a numerical simulation program using Matlab. Findings: We conduct an analysis of ARM attack in case of using multiple decoy antennas and these results can be used to decide the optimum positions of the decoys for anti-ARM. The findings indicate that the angle of deployment for the decoys in relation to the radar is a crucial element for effective radar protection. Improvements/Applications: The results from this study can enhance radar wave avoidance techniques by employing decoy antennas and will serve as foundational technology for future research in systematic radar defense methods.
