In this study, we provided electronic beam steering results for a circular array mainly to demonstrate the capability of the testbed and to investigate the fundamental properties of a conformal array manifold and currently not to compare patterns using electronic beam steering of the planar array with that obtained using the commutative beam steering of the circular array.

That is to say, for a spherical conformal array constituting of M concentric circular arrays, the total number of variables to be optimized can be reduced to 5 x (M +1), which can significantly alleviate the burden of the algorithm in the optimization process.

Mutual coupling calibration for a conformal array is more complicated, and few researches have been involved in this problem so far.

Low profile printed antennas flush mounted on curved surfaces such as cylinders and spheres represents an important class of conformal arrays that have been used in radar and communication systems [10].

Since graduation, he has been with Rome Air Development Center, now called Rome Laboratory, working on problems of airborn conformal array and methods of testing large arrays.

The array factor for such a bent or conformal array is given in [10] and repeated here for convenience

If the steering vector of the array is incomplete (Conformal array has the "shadow effect" due to the metallic cylinder, meaning that only the incident wave from a special angle, rather than all the antenna elements can receive this signal), the performance of MUSIC algorithm deteriorates quickly [15].

First, in Section 2, the signal model of arbitrary conformal array configurations with polarized antenna elements is introduced.
