  clutter
Therefore, using the antenna in the GPR system can improve the signal-to-clutter ratio and the dynamic range of the system.
      
Based on the researches of multi-information fusion, some simulations, identification, and information extractions of the targets from complex background clutter scenes are studied.
      
Untying of Clutter-Family Supports and Its Role in the Monotone-Structure Reliability Theory
      
We suggest a transformation of supports of a clutter family.
      
It is a natural generalization of the untying transformation of a one-clutter support previously introduced by the author.

On Extreme Disentanglement of Clutters in the Polesskii Estimates of the Boundaries of Combinatorial Reliability of Random Binar
      
An adaptive wavelet packet transform (AWPT) algorithm is proposed to process synthetic aperture radar (SAR) imagery and remove background clutters from target images.
      
Consequently, clutters can be more effectively separated from the desired target features in the transform domain than in the original SAR domain.
      
These clutters induce a strong effect in millimeter wave band and the signal-versus-clutter ratio (SCR) is therefore deteriorated at the receiving terminal.
      
However, this approach is prone to errors caused by distractions such as occlusions, background clutters and multi-object confusions.

  ground clutter
To suppress the ground clutter, for airborne early warning (AEW) radars is the key technique in radar signal processing.
      
In such an effect, the range-dependent ground clutter spectrum can be easily aligned, and Space-Time Adaptive Processing (STAP) is to be more applicable and effective for the Ground Moving Target Indication (GMTI) in bistatic systems.
      
The new waveform is shown to have good ability to suppress ground clutter and good Electronic Counter-CounterMeasures (ECCM) ability as well.
      
Ground clutter does not principally interfere with RASS echoes due to their big frequency shift.
      
Therefore, RASS can supplement radar wind profilers at lower levels where clear-air echoes may be not detectable due to ground clutter.

  cluttered
The robot is started in completely unknown and cluttered environments.
      
As a reptile animal crawls in a cluttered environment, so a quadruped robot should be able to crawl on an irregular ground profile with its static stability by adopting the straightgoing and standstill-turning free gaits.
      
This feature enhances the maneuverability of the Cycab in cluttered environments.
      
Studies investigating this question, however, have generally only examined reaches to single objects presented in isolation, even though natural prehensile movements are typically directed at objects in cluttered scenes which contain many objects.
      
The intensity of one information source (vehicles in Experiment 1, destinations in Experiment 2) was varied to examine the effects of salience and discrimination on both searching for and processing the information in a cluttered display.
