as.echosounder {oce} | R Documentation |
Coerces a dataset into a echosounder dataset.
as.echosounder(time, depth, a, src = "", sourceLevel = 220, receiverSensitivity = -55.4, transmitPower = 0, pulseDuration = 400, beamwidthX = 6.5, beamwidthY = 6.5, frequency = 41800, correction = 0)
time |
times of pings |
depth |
depths of samples within pings |
a |

src |
optional string indicating data source |
sourceLevel |
source level, in dB (uPa at 1m), denoted |
receiverSensitivity |
receiver sensivity of the main element, in
dB(counts/uPa), denoted |
transmitPower |
transmit power reduction factor, in dB, denoted
|
pulseDuration |
duration of transmited pulse in us |
beamwidthX |
x-axis -3dB one-way beamwidth in deg, denoted |
beamwidthY |
y-axis -3dB one-way beamwidth in deg, denoted |
frequency |
transducer frequency in Hz, denoted |
correction |
user-defined calibration correction in dB, denoted
|
Creates an echosounder file. The defaults for e.g. transmitPower
are taken from the echosounder
dataset, and they are unlikely to make
sense generally.
