Programs for working with Grape1 Digital RF datasets.
DRF_reader.py reads a 24-hour Digital RF spectrum dataset; it processes through 1440 minutes. For each minute, the system fills the array named 'data' with 600 32-bit float complex values (I/Q).
plotspectrum_V4a.py reads ina DRF dataset and plots it as a spectrogram - in this case, a waterfall plot showing 24 hours and Doppler excursions of the carrier signal being tracked. Input:
-f name of top-level directory (must be the directory above the ch0 level)
-p path to an output directory where the plot will be saved.
Example: python3 plotspectrum_V4a.py -f C:\\temp\\OBS2023-11-01T00-00 -p C:\\temp\\myplotfile.png
The escape sequences "\\" are mandatory for Python.
