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.
Typed bridge of the rangedoppler op `fmcw_range_profile into the 2-D evolution registry: the same implementation, called under the op(v, a, b) convention. This op has no tunable parameter; a and b` are unused.
