fmcw_range_profile — RANGEDOPPLER process op

• 資料種類:beatcube → signal

• 呼叫:import rangedoppler; rangedoppler.fmcw_range_profile(cube, chirp=None, antenna=None, normalize=False)(或 opsrangedoppler.get("fmcw_range_profile"))

用法

僅距離的剖面:快時間 FFT 的振幅,在其餘軸上平均。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

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.
