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 ...

What is Signal-to-Noise Ratio and Why Should Writers Care
WebOct 1, 1986 · The ratio between the Doppler signal issuing from the range cell and that from the mobile clutter targets will be defined as the signal-to-mobile clutter ratio (SCR) m. We … 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. Clutter folding becomes a problem when the range extent of the … See more WebUltrasound plane-wave imaging (PWI) can significantly increase the frame rate and thus realize ultrafast imaging (>1000 frames per second) [].It has been widely studied because of the increasing need for high frame rates in medical ultrasound imaging over the past several decades [2,3].Nevertheless, the absence of transmit focusing leads to a low signal-to … dialysis delivery packages
