Abstract

In this study, motion compensation for electronic beams in sea environments is proposed. Because the radar on a ship fluctuates according to the sea environment, it is necessary to compensate for the fluctuation to achieve accurate beam steering. Unlike the fluctuations in the pitch and yaw directions, where only compensation for the beam steering value is required, the fluctuation in the roll direction causes the beam to rotate. Therefore, compensation for the rotation of the beam in the roll direction is necessary. For this purpose, beam rotation and 2-D beam steering were performed. Finally, the proposed method is applied to a 20×20 array and verified.
