Sdr To Dxf -
# Pseudocode: map IQ points to DXF polylines points = iq[::100] # decimate with open("constellation.dxf", "w") as f: f.write("0\nSECTION\n2\nENTITIES\n") for p in points: f.write(f"0\nPOINT\n10\n{p.real}\n20\n{p.imag}\n0\n") If you have a or a particular signal type in mind (ADSB, NOAA APT, POCSAG, FT8, etc.), I can help outline exactly how to turn it into a meaningful DXF drawing.
Would you like a Python script example that reads IQ data and exports a DXF with amplitude contours or phase vectors? sdr to dxf
For constellation art:
# Record IQ from RTL-SDR rtl_sdr -f 100e6 -s 2.4e6 -n 10e6 iq_data.bin python -c "from matplotlib import pyplot as plt; import numpy as np; iq=np.fromfile('iq_data.bin', dtype=np.complex64); plt.specgram(iq); plt.savefig('spec.png')" Trace to vector potrace -b dxf spec.png -o output.dxf # Pseudocode: map IQ points to DXF polylines
It sounds like you're looking for something interesting or notable about converting (Software-Defined Radio) data or recordings to DXF (Drawing Exchange Format, a CAD file format). import numpy as np
