Abstract :
The surface errors of a deployable mesh antenna are measured. A measurement method which eliminates the gravity effect is presented which is based on the near-field antenna measurement technique (D.M. Kerns, 1978) and Fourier series expansion in the polar coordinate fixed to measurement systems.<>
