Dispersive constant false alarm rate receiver
Proceedings of the IEEE, 1972Search radars require a constant false alarm rate (CFAR) receiver to compensate for changes in noise and clutter levels. A CFAR circuit is described which uses matched dispersive delay lines flanking a hard limiter. The circuit's operation is discussed and plan-position indicator (PPI) photographs are shown which illustrate its effectiveness.

Constant false alarm rate detector based on the maximal reference cell
Digital Signal Processing, 2013In order to improve the detection performance of constant false alarm rate (CFAR) detectors in multiple targets situations, a CFAR detector based on the maximal reference cell (MRC) named MRC-CFAR is proposed. In MRC-CFAR, a comparison threshold is generated by multiplying the amplitude of MRC by a scaling factor. The number of the reference cells left,

A Design Generator of Parametrizable and Runtime Configurable Constant False Alarm Rate Processors
2021 28th IEEE International Conference on Electronics, Circuits, and Systems (ICECS), 2021Constant false alarm rate (CFAR) algorithms are widely used in radar signal processing for object detection in cluttered and noisy environments and their fast hardware implementation is required in many of the real time applications. For that purpose, a parametrizable and runtime reconfigurable generator of CFAR detectors, featuring fully streaming I/O

Constant false alarm rate detection in Pareto Type II clutter
Digital Signal Processing, 2017Abstract Recent investigations have shown that the Pareto class of models provide a valid approximation for the statistical structure of the backscattering from the sea, for high resolution X-band maritime surveillance radar. This has stimulated the research and development of non-coherent radar detection processes for operation in such a clutter ...

Constant False Alarm Rate Detectors
2010The process of detecting a target begins with comparing a radar measurement with a threshold. Measurements exceeding the threshold are associated with returns from a target, and measurements below the threshold are associated with thermal noise or other interference sources including intentional jamming and background returns from terrain and bodies of

A robust anomaly detection method using a constant false alarm rate approach
Multimedia Tools and Applications, 2020With the rapid growth of information and communication technologies, the number of security threats in computer networks is substantially increasing; thus, the development of more proactive security warning measures is required. In this work, we propose a new anomaly detection method that operates by decomposing TCP traffic into control and data planes,

Signature adaptive mine detection at a constant false alarm rate
SPIE Proceedings, 2001A constant false alarm rate algorithm has been developed for use in multi-band mine detection. While it is often difficult to predict the spectral signatures of targets, the shape of the target may be known. This test exploits geometric target features and spectral differences between the target and the surrounding area. The algorithm is derived from a

An adaptive order statistic constant false alarm rate detector
IEEE International Conference on Systems Engineering, 1989An adaptive order statistic (AOS) detector is proposed which acts as an order statistic detector but whose parameter k is chosen according to the outcome of a hypothesis test that attempts to detect the presence of a clutter power transition within each reference window.

General transformation approach for constant false alarm rate detector development
Digital Signal Processing, 2014Abstract A general result is derived, allowing the transformation of incoherent constant false alarm rate detection processes from a given clutter environment to that of any clutter model of interest. This generalises recent work where detection processes for Pareto distributed clutter are developed in a similar way.

Constant False Alarm Rate (CFAR) Detection in Weibull Environment
2007 IEEE 15th Signal Processing and Communications Applications, 2007In this work, the performance of N pulse radar receivers which use Post Integration (PI) and Binary Integration (Bl) algorithms is analysed in homogeneous Weibull environment. It is assumed that the shape parameter of the Weibull distribution is known a priori.
