What causes radar ground clutter?
Ground clutter is usually from objects close to the ground since the radar beam starts close to the ground the further out the radar beam goes to higher elevations as you move away from the radar site.
What is sea clutter on radar?
Sea clutter refers to the radar returns from a patch of ocean surface. Accurate modeling of sea clutter and robust detection of low observable targets within sea clutter are important problems in remote sensing and radar signal processing applications.
How many types of clutter are there in radar?
Types of Clutter Clutter is caused by a variety of objects and phenomena and can be categorized into three major categories: surface clutter, volume clutter, and point clutter. Radar clutter detection can help eliminate these distractions from the true signal.
How do you reduce clutter on radar?
The results show radar clutter can be mitigated either by reducing the ground area illuminated by the antenna, in the case of surface clutter, or by reducing the pulse duration, in the case of volume clutter.
How do you identify ground clutter?
One way the ground clutter issue is dealt with is by the use of multiple radars. This can help determine the characteristics of the ground clutter and if hydrometeors are also present in that area.
What is the difference between noise and clutter?
Unwanted signals in a search radar are generally described as noise and clutter. (Noise was discussed earlier in detail concerning the Radar Basics.) Clutter is the term used and includes ground returns, sea returns, weather, buildings, birds and insects. The definition of clutter depends on the function of the radar.
What is clutter level?
The Clutter–Hoarding Scale® is an assessment measurement tool, developed by the Institute for Challenging Disorganization® (ICD®) to give professional organizers and related professionals definitive parameters related to health and safety.
What are some types of clutter that may appear on radar imagery?
Radar Clutter
- Surface Clutter – Ground or sea returns are typical surface clutter.
- Volume Clutter – Weather or chaff are typical volume clutter.
- Point Clutter – Birds, windmills and individual tall buildings are typical point clutter and are not extended in nature.
What is a clutter map?
Clutter/Land Use Map. A term “Clutter” refers to a Land Use/Land Cover classification of surface features. They are classified into different classes: classes of built-up areas, water classes, classes of landscape and vegetation.
What are clutters?
Definition of clutter : to fill or cover with scattered or disordered things that impede movement or reduce effectiveness a room cluttered with toys —often used with up Too many signs were cluttering up the street corner. clutter.
What is RF clutter?
Clutter describes obstacles which will impede a signal’s path. For RF planning purposes this can be trees and buildings. As trees and buildings vary greatly in density we need different types.
What is media clutter?
Advertising or marketing clutter refers to the large volume of advertising messages that the average consumer is exposed to on a daily basis.
What is clutter in data visualization?
Visual clutter denotes a disordered collection of graphical entities in information visualization. Clutter can obscure the structure present in the data. Even in a small dataset, clutter can make it hard for the viewer to find patterns, relationships and structure.
How does radar clutter detection work?
Radar clutter detection can help eliminate these distractions from the true signal. Surface clutter is caused by the geography of the surrounding area. This radar ground clutter can be caused by uneven terrain, trees and other greenery, and even the texture or groundcover of the area (e.g. long grass vs. stone).
What is the difference between clutter and forward scatter for radar?
If the surface has some roughness, the forward scatter component is reduced by diffuse, non-coherent scattering in other directions. For monostatic radar, clutter is the diffuse backscatter in the direction towards the radar 5 5/157
How many radar bands are used in the analysis of ground clutter?
The results of the analysis of ground clutter, reported in this section, mainly relate to the data recorded with the MIT Lincoln Laboratory Phase One radar [29], [32]. The Phase One radar could operate in any one of five different radar bands (VHF, UHF, L-, S-, and X-bands).
