1. A composite tensor beamforming method for an electromagnetic vector coprime planar array, comprising:
step 1: building the electromagnetic vector coprime planar array, and receiving a signal by the electromagnetic vector coprime planar array;
step 2: performing tensor modeling of the signal received by the electromagnetic vector coprime planar array;
step 3: designing a three-dimensional weight tensor corresponding to a coprime sparse uniform sub-planar array;
step 4: forming a tensor beam power pattern of the coprime sparse uniform sub-planar array; and
step 5: performing tensor beamforming by the electromagnetic vector coprime planar array based on coprime composite processing of the sparse uniform sub-planar array, and emitting a tensor beam with the tensor beam power pattern by the electromagnetic vector coprime planar array.
