Abstract :
A partially coherent array (PCA) is proposed for achieving high angular resolution. This array is considered to have mostly noncoherent channels. With a limitation on the field of view of the imaging array, the missing phases of the noncoherent channels can be reconstructed through an iterative Fourier transformation process. After this process a PCA can perform imaging like a totally coherent array.<>
