Embodiment 1
[0036] The present invention aims to provide a method, system, device and medium for acquiring a direction-finding angle of a dual-polarized antenna array. In the method, by designing an orthogonal base station dual-polarized antenna array to receive the radiated electromagnetic wave signal of the mobile terminal, comparing the magnitude of the signal amplitude measurement value of each receiving end of the antenna array element, selecting the received signal with a higher polarization measurement value, and combining this The phase measurement value of each element of the antenna array under polarization is used as the angle parameter to estimate the initial value of the phase. At the same time, the phase consistency value in the preset angle range under the polarization matching state of the antenna array element is obtained by the darkroom measurement method, and the phase consistency value is reversed to form the phase error compensation value of the antenna array element. ...
