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 Web1 de jun. de 1997 · The validity of the compound model has been proven for VV polarisation both for amplitude and correlation properties.

Every … WebClutter echoes can be many orders of magnitude larger than target echoes. An MTI radar exploits the relatively high Doppler frequencies of moving targets to suppress clutter echoes, which usually have zero or very low Doppler frequencies. A typical MTI radar uses a high-pass filter to remove energy at low Doppler frequencies.
