With set_doppler_num_bins(), acq_grid holds the Doppler candidate columns
followed by 0, 1 or 2 noise-reference columns placed at doppler_center
+/- the configured doppler_max, outside the linear Doppler axis. Nothing
in the dump said how many columns were candidates, so the readers either
rejected the file (Acquisition_Dump_Reader) or plotted the reference
columns on a wrong Doppler axis (plot_acq_grid.py, plot_acq_grid.m).
Write a new doppler_num_candidates variable to the dump and use it in
the readers to keep only the candidate columns. Dumps without it are
read as before, except that the reference column of older narrowed
dumps is also skipped. The Python and MATLAB scripts plot a
single-candidate (narrowed) grid as a code-delay line instead of an
empty surface.
Add a regression test that reads back a full-grid dump with two
reference columns and a narrowed N = 5 dump.
- Added a plot_positive_acq filter option, to enable plotting only the positive
acquisitions.
- Improved the file path processing. Previous version used hardcoded character
offset that will not work if someone sets custom dump prefix. Now we use
python's built-in pathlib and split-parse using the "_" separator.
- The scripts used to use two different ways of encoding system,channel,chips,
one with python dict another with massive if-else nest. This has been uniformed.
- The script used to assume all files in the dump folder would be acquisition dump
but now we filter for acq dumps using pathlib's glob()
