In this paper, we proposed a calibration algorithm based on dual-polarized cylindrical conformal array with un-knowing mutual coupling. Combined with the characteristics of cylindrical array, the elevation can be estimated based on GEESE algorithm. Then, the azimuth estimation can be obtained after projection transformation and smoothing. In general, the proposed algorithm can realize joint estimation of angle information, polarization parameters and mutual coupling coefficients through iteration. Simulation results confirm the effectiveness of the algorithm.
