Signal to clutter and noise ratio
WebApr 14, 2024 · The estimation of Signal-to-Clutter Ratio (SCR) of a radar point target, such as a corner reflector, is an essential step for synthetic aperture radar (SAR) interferometry … WebThe basic idea behind this method is that the significant wave height is linearly dependent on the square root of the signal-to-noise ratio, ... The proposed method to estimate wave heights is validated using data sets of sea clutter images measured by a marine radar and significant wave heights derived from measurements taken by a buoy used as ...

WebApr 8, 2024 · This structure reduces the energy received by the individual pixel. Relatively, the noise component in the remote sensing imaging chain enhances the interference with the imaging quality integrally, resulting in a significant decrease in the signal-to-noise ratio (SNR) of the imaging results compared with the ideal RSIs, as shown in Figure 1. WebThe aim of this study was to evaluate the signal-to-noise ratio (SNR) in IOFF as a function of the distance between a LED and a ... 8 and 10 mm. To obtain a useful signal, we used the spectral approach to remove noise. The best signals were obtained at a distance of 10 mm (SNR median is 63). Good quality signals were also obtained at ...
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 … http://ece-events.unm.edu/amerem2014/Resources/taggedABSTRACTS/065.pdf
If the Clutter Return Power is greater than the System Noise Power then the Radar is clutter limited and the Signal to Clutter Ratio must be equal to or greater than the Minimum Signal to Noise Ratio for the target to be detectable. ... Halving the distance will cause the signal to noise ratio to increase (improve) by a … See more Clutter is a term used for unwanted echoes in electronic systems, particularly in reference to radars. Such echoes are typically returned from ground, sea, rain, animals/insects, chaff and atmospheric turbulences, … See more In addition to any possible clutter there will also always be noise. The total signal competing with the target return is thus clutter plus noise. In practice there is often either no clutter or clutter dominates and the noise can be ignored. In the first case the radar is said to … See more The surface clutter return depends upon the nature of the surface, its roughness, the grazing angle (angle the beam makes with the surface), the frequency and the polarisation. The … See more What one person considers to be clutter, another may consider to be a target. However, targets usually refer to point scatterers and clutter to extended scatterers (covering … See more Rain, hail, snow and chaff are examples of volume clutter. For example, suppose an airborne target, at range $${\displaystyle R}$$, … See more Clutter folding is a term used in describing "clutter" seen by radar systems.

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 …
