This array steering vector be all array elements of antenna to thering is the response of unit energy arrowband information source, array steering vector is relevant with the geometry of the array of antenna.For example, for even linear array, M array element is equidistantly arranged in straight line, and array element distance is d.Suppose that a travelling carriage is positioned at far field, the wavefront that its signal arrives each array element is plane wave.Arrive wave line of propagation angle θ (with the angle theta of array normal) and be called direction of arrival, θ is the deflection angle between target level azimuth and reference azimuth in embodiments of the present invention, in the time that reference azimuth is 0 degree azimuth, θ is target level azimuth.The array steering vector of this even linear array is:
[ 1 , e - j 2 π λ d sin θ , . . . , e - j 2 π λ ( M - 1 ) d sin θ ]
Represent take first array element as benchmark, other array elements phase place with respect to the first array element on varying level azimuth changes.
Figure BDA0000474339080000072
represent the array element distance take wavelength as unit.
This guiding adjustment amount vector is the conjugation of this array steering vector under this deflection angle.This steering vector adjustment amount is relevant with array pitch and the operating frequency of this deflection angle, antenna.This is due to according to the pattern multiplication principle of antenna array, directivity function × battle array directivity function of the directivity function=antenna element of antenna, this gust of directivity function refers to the product of guiding adjustment amount vector array steering vector in embodiments of the present invention, in the case of the value of the directivity function of antenna element is definite, the value maximum of the directivity function of antenna when lower gust of directivity function value of this deflection angle is maximum, in the time that guiding adjustment amount vector is the conjugation of array steering vector under this deflection angle, battle array directivity function value maximum, therefore, this guiding adjustment amount vector is the conjugation of this array steering vector under this deflection angle in embodiments of the present invention.

Particularly, can the weights of this broadcast beam be sent to base station according to Antenna Interface Standards Group (Antenna Interface Standards Group, AISG) agreement.Multiply each other these weights just can obtain pointing to the azimuthal broadcast beam of this target level with the information receiving in base station.
Therefore, the device of the weights of the generation antenna of the embodiment of the present invention, by obtaining standard weight vector, determine guiding adjustment amount vector phase place correction vector, according to standard weight vector, guiding adjustment amount vector phase place correction vector, the impact of the beamwidth of the antenna element of antenna can be revised, thereby the weights that point to the azimuthal broadcast beam of target level can be generated exactly.
