Test Dual-Bearing Solutions Using MUSIC Algorithm

This function applies a sequence of tests (P1, P2, and P3) to validate dual-bearing solutions derived using the MUSIC algorithm. The tests evaluate the quality of solutions based on eigenvalue ratios, signal power ratios, and covariance matrix power ratios.

Usage

seasonder_MUSICTestDualSolutions(seasonder_cs_object)

Arguments

seasonder_cs_object

A SeaSondeRCS object containing MUSIC solutions and related data.

Value

The updated SeaSondeRCS object with validated dual-bearing solutions and recorded processing steps.

Details

The function applies the following sequence of tests:

1. P1: Eigenvalue Ratio Test:

   • Evaluates the ratio between the largest and second-largest eigenvalues.

2. P2: Signal Power Ratio Test:

   • Validates the ratio of signal powers for dual-bearing solutions.

3. P3: Signal Matrix Power Ratio Test:

   • Checks the ratio of diagonal to off-diagonal powers in the covariance matrix.

Each test updates the MUSIC solutions in the input object, marking solutions that fail the tests as "single." The function also logs the start and end of the testing process as part of the object's processing steps.
