Compute First Order Regions (FOR) Using the SeaSonde Method

This function processes a SeaSondeRCS object to compute the First Order Regions (FOR) using the SeaSonde method. The workflow includes detecting null points, filtering amplitudes, limiting currents to a maximum range, and rejecting peaks based on proximity to Bragg indices and noise/ionospheric contamination.

Usage

seasonder_computeFORsSeaSondeMethod(seasonder_cs_object)

Arguments

seasonder_cs_object

A SeaSondeRCS object containing the spectral data and configuration parameters.

Value

The updated SeaSondeRCS object with the computed First Order Regions (FOR).

Details

Workflow Steps:

1. Initialize Processing Steps:

   • Marks the start of the SeaSonde method processing in the object's metadata.

2. Detect Null Points:

   • Locates the nulls defining the First Order Regions (FOR) using seasonder_findFORNulls.

3. Filter Amplitudes:

   • Removes regions with insufficient amplitudes using seasonder_filterFORAmplitudes.

4. Limit Currents to Maximum Range:

   • Ensures that currents exceed the configured maximum radial velocity using seasonder_limitFORCurrentRange.

5. Reject Distant Bragg Peaks:

   • If enabled, rejects peaks that are too far from Bragg indices using seasonder_rejectDistantBragg.

6. Reject Noise/Ionospheric Peaks:

   • If enabled, removes peaks where non-Bragg power significantly exceeds Bragg power using seasonder_rejectNoiseIonospheric.

7. Finalize Processing Steps:

   • Marks the end of the SeaSonde method processing in the object's metadata.

Use Case: This function is designed for processing SeaSonde radar data to accurately identify and validate the First Order Regions, ensuring reliable current and wave measurements.
