SimradEK60.jl

Introduction

Based on SimradRaw.jl, this project reads and intepretes Simrad EK60 RAW files, extracting power and phase angle information and allowing calculation of volume backscatter, Sv.

Example

using SimradEK60
using SimradEK60TestData
filename = EK60_SAMPLE
ps = SimradEK60.load(filename)
ps38 = [p for p in ps if p.frequency == 38000]
Sv38 = Sv(ps38) # Volume backscatter
al38 = alongshipangle(ps38) # Split beam angle
at38 = athwartshipangle(ps38)
_R = R(ps38) # Range / depth
_t = filetime(ps38) # timestamps
