A method of estimating the shape of a circular antenna disposing of boundary observations from sensors is given. The model is composed by a pair of equations: an elliptic partial differential one excited by a disturbing noise and the boundary condition one. The estimate is represented as a linear form in the sensor values to which a noise is added. By use of Green functions the residual of the minimizing problem is expressed in a closed form. Then, a rapidly convergent series for calculating the inverse of the elliptic operator is found. Some numerical examples confirm the validity of the proposed approach.
