setphasecalinfo(phasecalmethod, baselevel, fraclevel, windvelocity, timescale)
Description
The residual phase errors after calibration by the relevant method are a topic
of debate, especially for radiometric calibration. For radiometric phase calibration, we
assume the residual phase errors
are given by
= ,
|
(1.35) |
where b is some base error level related to the radiometer sensitivity, f is the fraction
of atmospheric phase errors which are not corrected,
D is the phase structure function, v is the wind velocity, and t is a
time scale for the atmospheric phase errors.
