Signal to clutter and noise ratio
WebWe consider four effects relevant to the determination of the ratio of radar signal to clutter and noise. These effects are atmospheric turbulence, target fluctuations based on the Swerling models, zero-mean Gaussian background and receiver noise, and lognormal-distributed clutter. Radar return signal levels are affected by target fluctuations and … WebJan 18, 2012 · However, in general, cell-based biosensors have low signal-to-noise (S/N) ratio due to the low signal of cellular responses. To solve this problem, not only must the sensitivity of sensors be improved but also the tactic biosensor cells need to be engineered using e.g., genetic engineering [ 6 , 7 ], cellular engineering [ 8 , 9 ], and cell culture …
