Liya,
Doppler shift Δf is proportional to both speed and carrier frequency /f/₀
Δ/f/ = /f/₀ · /v///c/₀,
where /v/ is the relative speed of your thing, and /c/₀ is the speed of
light.
The highest frequencies we can, so far, do radio communications on, are
in the range of f₀=150 GHz.
So, assuming you do communications on 150 GHz, for your Doppler shift to
be Δ/f=/10 GHz higher after 1s, your acceleration must been
/a = /Δ/f / f/₀ · /c/₀ / 1s = 10 GHz / 150 GHz · 3·10⁸ m/s / s = 2/30 ·
3·10⁸ m/s² = 1/15 /c/₀/s.
The fastest object mankind has ever built is the Parker Solar Probe,
which will burn up while it spirals into the sun, at a maximum velocity
of ca 1/15 of the speed of light. It takes it years to reach that speed,
not 1s.
So, you're assuming you're seeing a doppler from a satellite rotating
around earth that sees a relative acceleration higher than a "satellite"
around the sun actively being pulled into the sun by the sun's immense
gravity.
That sadly makes no physical sense!
Best regards,
Marcus

Greetings everyone,

I went through these grc files and tried to do drift_simulation, i
am not getting the way to get 10GHz/s using inspectrum and
frequency sink slope calculation i have attached the grc and
screenshots.
