CFAR Strategy Formulation and Evaluation Based on Fox’s H-function in Positive Alpha-Stable Sea Clutter

open access: yesRemote Sensing, 2020
The problem of target detection in impulsive non-Gaussian sea clutter has attracted a lot of attention in recent years. The positive alpha-stable (PαS) distribution has been validated as a suitable model for the impulsive non-Gaussian sea clutter.

A Low-Complexity Radar Detector Outperforming OS-CFAR for Indoor Drone Obstacle Avoidance

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
As radar sensors are being miniaturized, there is a growing interest for using them in indoor sensing applications such as indoor drone obstacle avoidance.

Detection of an unknown rank-one component in white noise [PDF]

open access: yes, 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 ...

Adaptive detection of distributed targets in compound-Gaussian noise without secondary data: A Bayesian approach [PDF]

open access: yes, 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 ...

A two stage beamforming approach for low complexity CFAR detection and localization for passive radar

open access: yes, 2022
S.1178-1182We propose a two stage beamforming technique for localisation of moving target in a passive radar environment. In order to perform localization and tracking in Cartesian plane, in addition to detection in the range Doppler domain, it is ...

Detection of very close targets by fusion CFAR detectors [PDF]

open access: yesScientific 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

open access: yesIEEE 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.

Adaptive detection with bounded steering vectors mismatch angle [PDF]

open access: yes, 2007
We address the problem of detecting a signal of interest (SOI), using multiple observations in the primary data, in a background of noise with unknown covariance matrix.

An Efficient CFAR Detector for Burr Type-XII Distributed SAR Ground Clutter

open access: yesIEEE Access
In 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 approach of constant false alarm ratio for improved target tracking [PDF]

open access: yesScientific 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.
