Adaptive censored greatest-of CFAR detection
IEE Proceedings, Part F: Radar and Signal Processing, 1992A new CFAR detection algorithm in which two tentative estimates of the noise level in the test cell are obtained by independently processing the outputs of the leading and the lagging cells is proposed and studied. The two tentative estimates are obtained by employing a cell-by-cell criterion for accepting or rejecting reference samples.

A new and robust CFAR detection algorithm
IEEE Transactions on Aerospace and Electronic Systems, 1992A constant false alarm rate (CFAR) detection method which is based on a combination of median and morphological filters (MEMO) is proposed. The MEMO algorithm has robust performance with small CFAR loss, very good behavior at clutter edges and high detection performance in the case of closely spaced narrowband signals (targets).

CFAR Outlier Detection With Forward Methods
IEEE Transactions on Signal Processing, 2007Separation or classification of signal-present samples from noise-only samples is studied. The false-alarm probability implies how many noise-only samples are wrongly classified as outliers, and typically it should be smaller than some upper limit. The noise distribution parameters are not known a priori and have to be estimated. Multiple outliers have

Adaptive CFAR detection of multidimensional signals
2001 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.01CH37221), 2002Adaptive detection of multidimensional signals in the presence of interference with unknown covariance matrix is an expanding topic in a variety of scenarios ranging from radar/sonar to digital communication systems. We attack the problem of detecting a multidimensional radar signal, modeled as an unknown N/spl times/H matrix, embedded in Gaussian ...

An improved CFAR algorithm for target detection
2017 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS), 2017The constant false alarm rate (CFAR) technique plays a key role in radar automatic detection process. The cell averaging (CA) CFAR procedure suffers from the masking effect in almost all the multitarget situations. The smallest of cell averaging (SOCA) CFAR has a better performance only when the interfering targets are present in the front or the rear ...

OS characterization for local CFAR detection
IEEE Transactions on Systems, Man, and Cybernetics, 1991An order-statistic (OS) characterization for modeling clutter statistics at local detectors is presented. Important features of the OS characterization include its structure, which allows for parallel computations, and its degrees of freedom, which enable it to track various changes in the clutter statistics.

A time frequency approach to CFAR detection
2011 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT), 2011Simultaneous analysis of signals in time and frequency domains is a standard approach in many signal processing applications including some detection. Parameters of clutter, noise and interference, and in some cases Doppler specifications, are the basis for most of current CFAR target detection techniques.
