![]() Rain, hail, snow and chaff are examples of volume clutter. ![]() In the first case the radar is said to be Noise Limited, in the second it is Clutter Limited. In practice there is often either no clutter or clutter dominates and the noise can be ignored. ![]() The total signal competing with the target return is thus clutter plus noise. In addition to any possible clutter there will also always be noise. In principle, all that is required to estimate the radar return (backscatter) from a region of clutter is a knowledge of the volume or surface illuminated and the echo per unit volume, η, or per unit surface area, σ° (the backscatter coefficient).Ĭlutter-limited or noise-limited radar changes with time, while for ground clutter it stays the same. This means, the scenario moves away, i.e. This clutter gets also a Doppler- speed by the wind. Suppose you have a low-end PC that does not comply with the required system specifications. I highly recommend keeping it at high the ground looks more vibrant and dense. The clutter may fill a volume (such as rain) or be confined to a surface (like land). Sea-Clutter Sea-clutter are disturbing radar-echoes of sea wave crests. Clutter’s primary responsibility is to sharpen and tweak numerous ground objects, like grass, trees, and rocks. However, targets usually refer to point scatterers and clutter to extended scatterers (covering many range, angle, and Doppler cells). I recommend using my 'Mid-Detail Texture' modification alongside this mod. Second, the density of ground clutter has been adjusted to a level I felt was a reasonable compromise between aesthetics and performance. In this guide, we'll walk through each setting and which are worth sacrificing to boost overall performance. OPTIMIZED CLUTTER is an attempt to first and foremost, extend the draw distance of ground clutter. What one person considers to be clutter, another may consider to be a target. You can either set this to Low, Medium, High or Very High, which sets all of the individual settings to the same level, or fine-tune visual quality by changing the settings one by one. 4.5 General problems in calculating surface clutter.4.3 Problems in calculating clutter for the pulse length limited case.3.1 Problems in calculating signal to volume clutter ratio.2 Clutter-limited or noise-limited radar Radar ground clutter spectral measurements at Lincoln Laboratory to levels 60 to 80 dB below the peak zero-Doppler level indicate that the shapes of the spectra often decay at rates close to exponential.
