Shape Adjustment of a Large Planar Phased Array Antenna With Nonlinear Cable Actuators
International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.Shape adjustment of large planar phased array antennas is significant because the shape distortion of phased arrays can greatly reduce the antenna’s gain in the observing direction. This study selects the inherent diagonal cables driven by motors as actuators, initially used to improve the stiffness of the antenna structure. The shape adjustment can be
