Abstract
A novel kind of aperture synthesis, called the multiaspect aperture synthesis, is proposed for far-field reconstruction of a moving noise source from near-field measurements by a receiving array of finite length comparable with the source length. This kind of aperture synthesis is based on certain characteristics of the near-field spatial correlation function which is sensitive to the current locations of the source and the receiving system. The statistical characteristics of the reconstructed far-field pattern, as well as the effects of noise spectral power density bandwidth and the source velocity on the reconstructed source characteristics are studied. The corresponding numerical simulations are performed.
