Recursive Average Gain: The gain used when implementing a rolling average of the amplitude values of real cells seen during the SSI process. By default the SSI process does not provide the real signal strength of a target, instead it provides a synthetic value based on the numbers of times its been seen. By using setting the gain value we can receive the rolling average of the real target signal from multiple sightings. The gain controls how much of a new cell's amplitude is added to the rolling average.
