seasonder_MUSICCheckSignalPowers {SeaSondeR} | R Documentation |
Validate Signal Power Ratios Using MUSIC Algorithm
Description
This function implements the P2 test for solutions derived using the MUSIC algorithm. The test evaluates the ratio between the largest and smallest signal powers for dual-bearing solutions.
Usage
seasonder_MUSICCheckSignalPowers(seasonder_cs_object)
Arguments
seasonder_cs_object |
A SeaSondeRCS object containing the MUSIC solutions and related data. |
Details
The P2 test is based on the ratio of the largest signal power (P_{max}
) to the smallest signal power (P_{min}
):
Ratio = \frac{P_{max}}{P_{min}}
This ratio is compared to a threshold defined in the MUSIC parameters. Only solutions that meet the following criteria are retained:
The solution has two bearings.
The signal power ratio is below the threshold.
Solutions failing this test are marked as "single."
Value
The updated SeaSondeRCS object with the following modifications:
A new column
signal_power_ratio
in the MUSIC data.A logical column
P2_check
indicating whether each solution passes the P2 test.Updated
retained_solution
values for solutions that fail the test.
