This report describes the results of detailed statistical analysis of sea clutter data that were collected during the ESRL 38/97 trial, which was held off the Northern Australian coastline in February 1999. One of the trial's main objectives was to contribute to a database of experimentally collected clutter returns with radar system parameters that are comparable to those used in the Elta EL/M...

In high-resolution radar scenarios, the optimal detection of a fluctuating distributed-target is addressed, in a spherically invariant random vector clutter. The optimal binary integrator is derived from the generalized likelihood ratio test design procedure. The formula of the false alarm probability implies the constant false alarm rate property with respect to both the clutter power level an...

Knowledge of the clutter rate is of critical importance in multi-target Bayesian tracking. However, estimating the clutter rate is a difficult problem in practice. In this paper, an improved multi-Bernoulli filter based on random finite sets for multi-target Bayesian tracking accommodating non-linear dynamic and measurement models, as well as unknown clutter rate, is proposed for radar sensors....

A multichannel terrain observation by progressive scans (TOPS) synthetic aperture radar (SAR) system is capable of imaging a wider swath with a higher azimuth resolution for improved moving target detection. For TOPS SAR, due to antenna beam steering, the azimuth bandwidth of background clutter is much larger than the instantaneous signal bandwidth. To overcome this problem, a method referred t...

A binary clutter is the family of odd circuits of a binary matroid, that is, the family of circuits that intersect with odd cardinality a fixed given subset of elements. Let A denote the 0;1 matrix whose rows are the characteristic vectors of the odd circuits. A binary clutter is ideal if the polyhedron fx 0 : Ax 1g is integral. Examples of ideal binary clutters are st-paths, st-cuts, T -joins ...

A new method is presented for the suppression of intermittent clutter echoes in radar wind profilers. This clutter type is a significant problem during the seasonal bird migration and often results in large discrepancies between profiler wind measurements and independent reference data. The technique presented makes use of a discrete Gabor frame expansion of the coherently averaged time series ...

We present a physically-based clutter model for low frequency synthetic aperture radar that includes both distributed scatterers and large-amplitude discrete clutter. The model is used to generate a synthetic forest clutter scene comprised of two components, a background component and a heavy-tailed discrete component. Model parameters are based on characteristics of the scene, such as the rada...

A clutter (or antichain or Sperner family) L is a pair (V,E), where V is a finite set and E is a family of subsets of V none of which is a subset of another. Usually, the elements of V are called vertices of L, and the elements of E are called edges of L. A subset se of an edge e of a clutter is called recognizing for e, if se is not a subset of another edge. The hardness of an edge e of a clut...

The scattering of waves by a buried object is often obscured by the clutter around it. Such clutter can be attributed to the scattering by random rough surfaces and random discrete scatterers. Recent studies show that, because of the memory effect, the angular correlation function can suppress the effects of clutter and make the scattering by the buried object more conspicuous. In this paper, w...
