A New Polarimetric CFAR Ship Detection System
2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006The objective of the proposed work is to develop optimal polarimetric Constant False Alarm Rate (CFAR) detector for ship detection. Polarimetric transformations and decompositions, clutter analysis, modeling, Principal Component Analysis (PCA), and multi-CFAR detection are the necessary components of optimal polarimetric CFAR ship detectors.

Distributed Fuzzy CFAR Detection for Weibull Clutter
IEICE Transactions on Communications, 2008In Distributed detection systems, restricting the output of the local decision to one bit certainly implies a substantial information loss. In this paper, we consider the fuzzy detection, which uses a function called membership function for mapping the observation space of each local detector to a value between 0 and 1, indicating the degree of ...

Environment detection with Kalman filter for CFAR detectors
2012 18th Asia-Pacific Conference on Communications (APCC), 2012The constant false alarm rate (CFAR) detector is a representative detection method for radar systems. Its detection performance is severely depending on clutter environments such as homogeneous and non-homogeneous. Depending on the environment, we have to adopt different CFAR algorithms.

CFAR detection of chirplets in coloured Gaussian noise
2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004Two detectors based on the GLRT (generalized maximum likelihood ratio test) are presented to detect a chirplet in coloured Gaussian noise for known and unknown covariance structures, respectively. They are applied to detect multiple chirplets by atomic decomposition, which is modified to account for the operating conditions of both detectors.

Robust CFAR detection in nonhomogeneous correlated interference
[Proceedings] ICASSP-92: 1992 IEEE International Conference on Acoustics, Speech, and Signal Processing, 1992Among the few adaptive filtering algorithms which have an embedded constant false alarm rate (CFAR) performance feature, the generalized likelihood ratio (GLR) test algorithm has been found to be robust in the non-Gaussian interference. The detection performance of the GLR algorithm is examined in nonhomogeneous/nonstationary interference environments ...

Matched subspace CFAR detection of hovering helicopters
IEEE Transactions on Aerospace and Electronic Systems, 1999A constant false alarm rate (CFAR) strategy for detecting a Gaussian distributed random signal against correlated non-Gaussian clutter is developed. The proposed algorithm is based on Scharf's matched subspace detector (MSD) and has the CFAR property with respect to the clutter amplitude probability density function (apdf), provided that the clutter ...

A multistage STAP CFAR detection technique
Proceedings of the 1998 IEEE Radar Conference, RADARCON'98. Challenges in Radar Systems and Solutions (Cat. No.98CH36197), 2002This paper introduces a new method of partially adaptive CFAR detection. The processor implements a novel sequence of orthogonal subspace projections to decompose the Wiener solution in terms of the cross-correlation observed at each stage. The detection performance is evaluated in the general framework of space-time adaptive processing.

Performance of decentralized L-CFAR detection in inhomogeneous background
IEEE Transactions on Aerospace and Electronic Systems, 2000The problem of decentralized constant false alarm rate (CFAR) detection, with L-CFAR remote sensors, is considered. Following a previous paper, concerning the design and the analysis of such detection structure in homogeneous environment, we now assume that a detector, designed to operate with homogeneous background, is affected instead by clutter ...

Presented here is a large class of adaptive array detection algorithms with constant false alarm rate (CFAR), so that the false alarm rate can be set to any preassigned number without knowledge of the noise covariance matrix. This class map incorporate any usual method of cell averaging and any method for array weight vector synthesis.

We describe here a generic approach to CFAR processing, introduced in [74], which results in detection algorithms that tend to be robust to inhomogeneities in radar clutter. Termed as ensemble- or E-CFAR detection, it combines members from the family of known CFAR processors. It is simple and easy to implement.
