Package likelihoodDetectionModule.normalizer

Class NormalizerProcess

java.lang.Object

PamguardMVC.PamProcess

likelihoodDetectionModule.normalizer.NormalizerProcess

All Implemented Interfaces:

PamObserver, ProcessAnnotator

public class NormalizerProcess
extends PamProcess

This PamProcess implements the normalizer of the likelihood detector. The user can select either a DecayingAverage (exponential), or SplitWindow algorithm. Using the signal/background time constants from the bands passed in, the normalizer produces an estimate of the signal/background levels present in the input spectral band data.
