Response of the Receiving System,es the cross-correlations for the various antenna pairs. We show how the basic parameters of the system affect the output. Some of the effects were introduced in earlier chapters and are here presented in a more detailed development that leads to consideration of system design in Chaps. . and ..

Very-Long-Baseline Interferometry, to operate them independently with no real-time communication link. This was accomplished by recording the data on magnetic tape for later cross-correlation at a central processing station. The technique was called very-long-baseline interferometry (VLBI), a term recalling the earlier long-baselineCreatinine-Test 发表于 2025-3-25 21:40:45

Further Imaging Techniques,, the limitations of the visibility measurements. There are two principal deficiencies in the visibility data that limit the accuracy of synthesis images. These are (1) the limited distribution of spatial frequencies in . and . and (2) errors in the visibility measurements. The limited spatial frequparoxysm 发表于 2025-3-26 04:45:40

Related Techniques, and space science. Here we introduce a few of them, including optical techniques, to leave the reader with a broader view. All of these subjects are described in detail elsewhere, so here the aim is mainly to outline the principles involved and to make connections between them and the material deve
