We consider a troublesome form of nonisoplanatism in synthesis radio telescopes: noncoplanar baselines. We present a novel interpretation of the noncoplanar baselines effect as being due to differential Fresnel diffraction in the neighborhood of the array antennas. We have developed a new algorithm to deal with this effect. Our new algorithm, which we call ldquoW-projectionrdquo, has markedly supe... |
