Convert dB Values to Self-Spectra Power

Source: R/SeaSondeRCS.R
dB_to_self_spectra.Rd

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).

Value

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

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.

See also

self_spectra_to_dB for the inverse operation.
