Batch measurement and calibration method of DSRT three-axis low frequency antenna pointing error

Figure 2 shows antenna scanning track and solar track; Antenna scanning track: X axis is Time.mat; Y axis is Ant_ ace_ dec.mat； Z axis is Ant_ dec_ dec.mat; Sun track: X axis is Time.mat; The Y axis is hour_ angle.mat； Z axis is DECs.mat; Figure 4 shows the measured pattern and Gaussian fitting pattern of DSRT antenna. Measured direction chart, x-axis is x_ mesh_ clean_ odd； The y-axis is y_ mesh_ clean_ odd； The z-axis is z_ mesh_ clean_ odd； The Gaussian fitting diagram is, and the x-axis is x_ mesh_ clean_ odd； The y-axis is y_ mesh_ clean_ odd； Z axis is zz_ mesh_ clean_ odd； Figure 5 shows the dual-line polarization channel pattern of DSRT antenna.

The x-axis in the left figure is x_ mesh_ clean_ odd； The y-axis is y_ mesh_ clean_ odd； The z-axis is z_ mesh_ clean_ odd； Measured point diagram, x-axis is delta_ rac_ odd； The y-axis is delta_ dec_ odd； The z-axis is Amp_ data_ odd； The x-axis in the right figure is x_ mesh_ clean_ even； The y-axis is y_ mesh_ clean_ even； The z-axis is z_ mesh_ clean_ even； Measured point diagram, x-axis is delta_ rac_ even； The y-axis is delta_ dec_ even； The z-axis is Amp_ data_ even； Figure 6 is a two-dimensional Gaussian fitting pattern.
