cbh az swings 25sep12

last updated 29sep12

      Azimuth swings were done with the cband high receiver on 25sep12.
The setup was:
The data processing for each box:

Dynamic spectra:

The images show the dynamic spectra for the Clockwise (CW) and counter clockwise (CCW) az swings for each 172 MHz band.

CW swing
CCW swing
6074MHz 6074MHz
6224MHz 6224MHz
6374MHz 6374MHz
6524MHz 6524MHz
6674MHz 6674MHz
6824MHz 6824MHz
6974MHz 6974MHz

Birdie power vs azimuth.

    Birdies were identified by looking at the dynamic spectra. The avg power over the birdie bandwidth was computed and then plotted vs azimuth. The clockwise and counter clockwise swings were over plotted to see if the birdies repeated in azimuth (for this to happen then need to be stable in time).
