Detection of an unknown rank-one component in white noise [PDF]
, 2006 We consider the detection of an unknown and arbitrary rank-one signal in a spatial sector scanned by a small number of beams. We address the problem of finding the maximal invariant for the problem at hand and show that it consists of the ratio of the ...

Detection of very close targets by fusion CFAR detectors [PDF]
Scientific Technical Review, 2016 In this paper the new application results of Linear and NonLinear Fusion Constant False Alarm Rate (LF-CFAR and NLF- CFAR) detectors are presented. Detection of very close targets per azimuth and per range is considered.

Research on a New Comprehensive CFAR (Comp-CFAR) Processing Method
IEEE Access, 2019 Since the clutter statistics of marine radar are non-stationary and difficult to ascertain, the constant false-alarm rate (CFAR) processor based on some clutter statistical characteristics is hard to obtain the CFAR performance.

Detection in the presence of surprise or undernulled interference [PDF]
, 2007 We consider the problem of detecting a signal of interest in the presence of colored noise, in the case of a covariance mismatch between the test cell and the training samples. More precisely, we consider a situation where an interfering signal (e.g., a

An Efficient CFAR Detector for Burr Type-XII Distributed SAR Ground Clutter
IEEE AccessIn this paper, a CFAR target detection algorithm is proposed for Burr TypeXII-distributed Synthetic Aperture Radar (SAR) ground clutter amplitude data. We employ method of log-cumulants (MoLC) to estimate the clutter model parameters.

An ABORT-like detector with improved mismatched signals rejection capabilities [PDF]
, 2008 In this paper, we present a GLRT-based adaptive detection algorithm for extended targets with improved rejection capabilities of mismatched signals. We assume that a set of secondary data is available and that noise returns in primary and secondary data ...

An approach of constant false alarm ratio for improved target tracking [PDF]
Scientific Technical Review, 2020 Each radar has the function of surveillance of certain areas of interest. In particular, the radar also has the function of tracking moving targets in that territory with some probability of detection, which depends on the type of detector.

Analysis of Os-Cfar and Ml-Cfar for a detection of a target in a noisy environment
, 2023 The purpose of this work is to address the problem of detection in an inhomogeneous environment with clutter distributed in a homogeneous way for two types of detectors the OS and the ML-CFAR. The clutter is assumed to be a sea clutter represented by a Weibull distribution.

Detection of a signal in linear subspace with bounded mismatch [PDF]
, 2006 We consider the problem of detecting a signal of interest in a background of noise with unknown covariance matrix, taking into account a possible mismatch between the actual steering vector and the presumed one.

Adaptive detection of distributed targets in compound-Gaussian noise without secondary data: A Bayesian approach [PDF]
, 2011 In this paper, we deal with the problem of adaptive detection of distributed targets embedded in colored noise modeled in terms of a compound-Gaussian process and without assuming that a set of secondary data is available.The covariance matrices of the ...
