Initialize NULL Data Structure for SeaSondeR MUSIC Analysis
Description
This function initializes a NULL data structure for storing results of the MUSIC analysis in SeaSondeR. The structure is designed as a tibble with pre-defined columns for range cells, Doppler bins, and various MUSIC-related parameters.
Usage
seasonder_NULLSeaSondeRCS_MUSIC()
Details
The initialized tibble contains the following columns:
-
range_cell
: Numeric vector representing range cell indices. -
doppler_bin
: Numeric vector for Doppler bin indices. -
range
: Numeric vector for range values. -
freq
: Numeric vector for frequencies. -
radial_v
: Numeric vector for radial velocities. -
cov
: A list to store covariance matrices. -
eigen
: A list to store eigenvalue decompositions. -
projections
: A list to store projection matrices. -
DOA_solutions
: A list to store Direction of Arrival (DOA) solutions. -
eigen_values_ratio
: Numeric vector for the ratio of eigenvalues. -
P1_check
: Logical vector indicating if the P1 criterion is satisfied. -
retained_solution
: Character vector for the type of retained solution ("single"
or"dual"
). -
DOA
: A list to store final DOA results. -
lonlat
: A list containing a data frame with longitude (lon
) and latitude (lat
) values.
Value
A tibble with pre-defined columns and empty values, ready to be populated with MUSIC analysis results.
