seasonder_NULLSeaSondeRCS_MUSIC: Initialize NULL Data Structure for SeaSondeR MUSIC Analysis

In SeaSondeR: Radial Metrics from SeaSonde HF-Radar Data

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.
