Abstract: To improve the surface accuracy of the deployable mesh antenna and reduce profile adjustment,a surface adjustment method based on multiple neural networks was proposed.By analyzing the correlation and coupling mechanism of the new tension mesh antenna surface,an adjustment strategy was proposed for the first time.Taking a 10m mesh antenna as an example,the root mean square value of the surface was reduced from 5.4×10-3m to 1.1×10-3m,which verifies the effectiveness of this method.

Key words: neural net work, mesh antenna, surface accuracy, shape coupling, surface adjustment
