Construction device and method of circular antenna array

The invention relates to the technical field of automobile parts, in particular to a construction device and method of a circular antenna array. According to the invention, a 3D spatial distribution rule is adopted for setting a circular antenna array, an antenna spatial domain p belongs to R3 is set in a unified manner, and R3 is a 3D space; the placing positions of the 3D spatial distribution XYZ signals of the area array and the linear array of the circular antenna are set; the incoming wave direction of the target signal is determined by using a three-level graph multiplication device; a plurality of dipole antennas are vertically placed to form a circular array, and assignment is performed on signals; MRC combination of multiple antennas is achieved by correcting an input forming beamfactor W; the frequency domain equalization of the channel is executed to achieve the combination and demodulation of multiple antennas so as to complete the construction; according to the invention,beam scanning can be carr
