dB_to_self_spectra: Convert dB Values to Self-Spectra Power

In SeaSondeR: Radial Metrics from SeaSonde HF-Radar Data

Convert dB Values to Self-Spectra Power

Description

This function converts power values expressed in decibels (dB) to linear self-spectra power values. The conversion is based on the given receiver gain, which accounts for the radar system's amplification effects.

Usage

dB_to_self_spectra(dB_values, receiver_gain)

Arguments

dB_values	A numeric vector. The power values in decibels (dB).
receiver_gain	A numeric scalar. The receiver gain in decibels (dB).

Details

The conversion from decibels to linear power follows the equation:

P = 10^{(dB + G)/10}

where:

• \( P \) is the self-spectra power in linear scale,

• \( dB \) represents the power values in decibels,

• \( G \) is the receiver gain in decibels.

Value

A numeric vector of self-spectra power values in linear scale.

See Also

self_spectra_to_dB for the inverse operation.
