Abstract method, not to be called directly but expected to be overwritten by the child class :return:

_sicci_ice_retracker(range, wfm, indices)

_filter_results()

These thresholds are based on the SICCI code

pysiral.retracker.ocog.ocog_tail_shape(wfm, tracking_point, tail_pad=3)

From SICCI module

pysiral.retracker.ocog.ocog_func(wave, percentage, skip)

pysiral.retracker.ocog.ocog_properties(waveform: numpy.ndarray) → Tuple[float, float, float]

Computes the three OCOG properties center of gravity, amplitude & width of a waveform in range gate units.

Parameters:

waveform – The waveform array

Returns:

center of gravity (cog), amplitude & width
