Introduction

A Julia implementation of the aliased seabed detection algorithm described in Blackwell et al. (2019).

Example

using AliasedSeabed
using SimradEK60

# Load some 38 kHz data
filename = "JR280_-D20121202-T170437.raw"
ps = SimradEK60.load(filename)
ps38 = [p for p in ps if p.frequency == 38000]
_Sv = Sv(ps38) # Volume backscatter
ntheta = alongshipangle(ps38) # Split beam angle
nphi = athwartshipangle(ps38)

# Find aliased seabed
a = blackwell_asbmask(_Sv, ntheta, nphi)

You can’t perform that action at this time.
