High clutter
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, and can cause serious performance issues with radar systems. Ver mais 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 many range, angle, and Doppler cells). … Ver mais Rain, hail, snow and chaff are examples of volume clutter. For example, suppose an airborne target, at range $${\displaystyle R}$$, is within a rainstorm. What is the effect on the detectability of the target? First find the magnitude of the clutter return. Assume that … Ver mais Clutter folding is a term used in describing "clutter" seen by radar systems. Clutter folding becomes a problem when the range extent of the clutter (seen by the radar) exceeds the Ver mais 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 … Ver mais 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 … Ver mais WebThe provides a much more accurate representation of the diversity of heights within clutter classes - and an improved prediction result.
