PERFORMANCE OF MODIFIED ORDER-STATISTICS CFAR DETECTORS WITH NONCOHERENT INTEGRATION

open access: yes, 1993
The order statistics cell averaging (OSCA) constant false alarm rate (CFAR) detector and the order statistics greatest of (OSGO) CFAR detector have the good properties of the order statistics (OS) CFAR detector while the processing time of each detector ...

Design and experimental validation of knowledge-based constant false alarm rate detectors

open access: yes, 2007
This paper deals with the design and the analysis of constant false alarm rate (CFAR) detectors exploiting knowledge-based (KB) processing techniques. The proposed algorithms are composed of two stages.

Constant False Alarm Rate Processors Based On Censored Cell Average

open access: yes, 2019
In this study, the performance of constant false alarm rate (CFAR) processors and censorship techniques developed to increase the probability of detection in a nonhomogeneous environment was investigated. False alarm and detection probabilities of the

Clutter Map Constant False Alarm Rate Mixed with the Gabor Transform for Target Detection via Monte Carlo Simulation

open access: yesApplied Sciences
Radar detection is a technology frequently used to detect objects and measure the range, angle, or velocity of those objects. Several studies have been performed to improve the accuracy and performance of detection methods, but they encountered a strong ...

Constant false alarm rate detection in Spherically Invariant Random Processes

open access: yes, 2004
International audienceIn this paper, we use the theory of generalized likelihood ratio tests (GLRT) to study the adaptive version of the asymp-totical Bayesian Optimum Radar Detector (BORD) built with a covariance matrix estimate.

A New CFAR Detector Based on the EM Algorithm

open access: yes
This paper proposes a simple Constant False Alarm Rate (CFAR) approach relying on the expectation-maximization algorithm to deal with clutter edges. The possible signal backscattered from a target is modeled as an incoherent pulse train and the newly ...

A Constant False Alarm Rate Detection Method for Sonar Imagery Targets Based on Segmented Ordered Weighting

open access: yes
Achieving reliable target detection in the field of sonar imagery represents a significant challenge due to the complex underwater interference patterns characterized by speckle noise, tunnel effects, and low-signal-to-noise ratio (SNR) environments ...

Constant False Alarm Rate Processors Based On Range Ordered Statistics

open access: yes, 2019
Constant false alarm rate (CFAR) processors are used to detect radar targets in the background in which parameters in the statistical distribution are unknown and may not be stationary.
