Initialize object for modeling using the DCM.

Usage

dcm_initialize(
  object,
  frequency,
  radius_cylinder = NULL,
  radius_curvature = NULL,
  radius_curvature_ratio = 3,
  radius_cylinder_fun = "max",
  length = NULL,
  g = NULL,
  h = NULL,
  theta = NULL,
  sound_speed_sw = 1500,
  density_sw = 1026,
  alpha_B = 0.8
)

Arguments

object: FLS-class object.
frequency: Transmit frequency (kHz)
radius_cylinder: Optional input to override current shape radius.
radius_curvature: Numeric input for the radius of curvature
radius_curvature_ratio: Ratio between body length and the radius of curvature. Defaults to 3.0.
radius_cylinder_fun: Defines which radius value will be used from the radius vector. Defaults to "max", but also accepts "mean" and "median".
length: Body length (m).
g: Density contrast.
h: Sound speed contrast.
theta: Body orientation relative to the incident sound wave.
sound_speed_sw: Seawater sound speed (c_body, m s^-1).
density_sw: Seawater density (ρ_body, kg m³)
alpha_B: Numerical coefficient (α_B).
