DOI: 10.1155/ijap/8070799
Abstract: A broadband direction finding method based on circular time‐modulated array antennas (TMAs) is proposed, which utilizes the principle of phase correlation interferometer by analyzing harmonic components to obtain the phase difference between array elements. The… read more here.
