Worked Example
Verified calculation
Given:
- Numerator Band SNR = 100
- Denominator Band SNR = 80
- Radiometric Noise Correlation Coefficient = 0
Expected Result:
- Spectral Index SNR (Propagated) = 128.06248474866
Engineering Interpretation:
Under the given input conditions, the calculated result is: Spectral Index SNR (Propagated) = 128.06248474866 dimensionless.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
Formula / Method
Propagated = sqrt(pow(numerator band snr, 2) + pow(denominator band snr, 2)) / (1.0 + radiometric noise correlation coefficient * numerator band snr * denominator band snr / (sqrt(pow(numerator band snr, 2) + 1.0) * sqrt(pow(denominator band snr, 2) + 1.0)))Formula family: formula_geospatial_multispectral_band_ratio_signal_to_noise_ratio_snr_propagation_calculator
