In this paper, an antenna array composed of circular array and orthogonal linear array is proposed by using the design of long and short baseline "orthogonal linear array" and the circular array ambiguity resolution design of multi-group baseline clustering. The effectiveness of the antenna array in this paper is verified by sufficient simulation and experiment. After the system deviation correction work, it is found that in the L/S/C/X frequency bands, the ambiguity resolu-tion probability is high, and the phase difference system error between each channel is basically the same. The angle measurement error is less than 0.5°, and the positioning error is less than 2.5 km. Notably, as the center frequency increases, calibration consistency improves, and the calibration fre-quency points become applicable over a wider frequency range. At a center frequency of 11.5 GHz, the calibration frequency point bandwidth extends to 1200 MHz. This combined antenna array deployment holds significant promise for a wide range of applications in contemporary wireless com-munication systems.
