fmcw_range_profile — RANGEDOPPLER process op

• データ種: beatcube → signal
• 呼び出し: import fullseye as fs; fs.ledger.fmcw_range_profile(cube, chirp=None, antenna=None, normalize=False) (実装を直接呼ぶなら import rangedoppler; rangedoppler.fmcw_range_profile(cube, chirp=None, antenna=None, normalize=False)、台帳から引くなら opsrangedoppler.get("fmcw_range_profile"))

使い方

Range-only profile: the fast-time FFT magnitude, averaged over the rest.

The 1-D marginal of :func:range_doppler_map — what a static scene needs, and what a single chirp can give. Magnitudes are averaged (never the complex values) over chirps and antennas, so the average is independent of the target’s velocity and angle: |FFT| does not rotate with the Doppler phase, only the phase does.

Bin j is j * c*f_s/(2*S*N_s) metres. With normalize=True a bin-centred target of amplitude a peaks at exactly a.

chirp / antenna select one slice instead of averaging. Returns a 1-D float64 array of length n_samples — a plain signal, so :mod:dsp and :mod:funct1d (find_peaks, smooth_funct_1d_gauss, spectrum) apply to it directly.

Raises ValueError: as :func:range_doppler_map, plus an out-of-bounds chirp index.
