In arnejohannesholmin/echoIBM: Simulation of multibeam sonar data

Calculates the probability density function of the total intensity (square of pressure amplitude) from a finite number of sine waves of arbitrary individual amplitudes, given in Equation 64 of Barakat 1974, using the terminology of that paper.

Description

Calculates the probability density function of the total intensity (square of pressure amplitude) from a finite number of sine waves of arbitrary individual amplitudes, given in Equation 64 of Barakat 1974, using the terminology of that paper.

Usage

dBarakatI(
  h,
  beta_n2,
  magn = 1,
  N = 100,
  betadistr = c("seq", "flat"),
  max.memory = 1e+09
)

Arguments

h	is the argument (superimposed intensity).
beta_n2	is the vector of individual intensities, or a single number giving the number of significant scatterers.
N	is the number of positive roots of the Bessel function of the first kind.
max.memory	is the maximum memory occupied by the function before splitting into a loop for each value of 'r'.
