estimate_noise

echopype.clean.estimate_noise(ds_Sv, ping_num, range_sample_num, noise_max=None)

Estimate background noise by computing mean calibrated power of a collection of pings.

See remove_noise for reference.

Parameters

ds_Svxr.Dataset

dataset containing Sv and echo_range [m]

ping_numint

number of pings to obtain noise estimates

range_sample_numint

number of samples along the range_sample dimension to obtain noise estimates

noise_maxfloat

the upper limit for background noise expected under the operating conditions

Returns

A DataArray containing noise estimated from the input ds_Sv
