RCS Reduction For UAV Array

It is difficult to achieve the effect of raid target because of the large Radar Cross Section (RCS) of Unmanned Aerial Vehicle (UAV) group when carrying out military missions. This paper proposes a method to reduce RCS of UAV linear array. Based on the principle of array scattering pattern synthesis, this paper calculates the RCS of a linear array UAV group and optimizes the posture of the UAV through a multi-objective evolutionary algorithm so that the RCS of the UAV group is significantly reduced within the viewing angle. The simulation results show that the reasonable arrangement of UAVs significantly reduces the RCS of the group within the specified viewing angle range.
