Dewey, R., 1993, "The Effects of Correlated Noise in Phased-Array Observations of Radio Sources", https://hdl.handle.net/2014/35944, UNKNOWN, JPL Open Repository
Arrays of radio telescopes are now routinely used to provide increased signal-to-noise when obseving faint point sources. However, calculation of the achievable sensitivity is complicated if there are sources in the field of view other than the target source. These additional sou... |

Sovers, O., 1993, "Vertical Ocean Loading Amplitudes From VLBI Measurements", https://hdl.handle.net/2014/35464, UNKNOWN, JPL Open Repository
Vertical ocean loading amplitudes are determined by analysis of IRIS geodetic VLBI data. Vertical ocean loading amplitudes can thus be inferred from VLBI data at a level which improves the overall model, but detailed assessment of individual tidal components is presently obscured... |
