Based on real-valued property of the non-circular sources
a new virtual array beamforming method for the uniform linear array was proposed by extending the original array utilizing the conjugate data of the real array.By analyzing the performance of the method in adaptive beamforming
some improvements were made and a computation saving method was proposed.Preserving both the time and the direction information
the virtual array is very applicable for adaptive beamforming.It provides much better performance than the original array
such as better beam pattern
higher array gain and the abilities to restrain interferes more than the freedom degrees.Several computer simulations were provided for illustrating the advantages of the proposed method.
