Hardware architecture for adaptive filtering based on energy-CFAR processor for radar target detection

, 2010
A hardware architecture that implements an adaptive filter based on energy analysis of radar echoes to improve the detection of the Constant False Alarm Rate (CFAR) algorithm is presented. Signal processing based on energy analysis emphasizes the edge of

CFAR detection in K-distributed sea clutter

, 2008
Conventional fixed threshold detectors set a fixed threshold based on the overall statistical characteristics of the spatially uniform clutter over all ranges to give a specific probability of false alarm and detection.

CATM-CFAR detector in the receiver of the software defined radar [PDF]

Scientific Technical Review, 2014
This paper presents a model of the CATM-CFAR detector in the receiver of the software defined radar. The mentioned detector is named cell-averaging-trimmed-mean CFAR. It is a combination of cell-averaging and trimmed mean CFAR.

CFAR Different Schemes Behavior and Detection Performance of Moving Targets

, 2004
In this paper detection probability of different CFAR schemes CA, GO, SO, and OS-CFAR is computed via various values of false alarm probability. The CA-CFAR and GO-CFAR detection performance is superior over other schemes; OS-CFAR detection performance ...

Marine Radar Constant False Alarm Rate Detection in Generalized Extreme Value Distribution Based on Space-Time Adaptive Filtering Clutter Statistical Analysis

Remote Sensing
The performance of marine radar constant false alarm rate (CFAR) detection method is significantly influenced by the modeling of sea clutter distribution and detector decision rules. The false alarm rate and detection rate are therefore unstable.

The Software-Based Implementation of the CFAR Reciever for the Processing of the Radar Signal

Advances in Electrical and Electronic Engineering, 2007
The performance of a radar receiver is greatly dependent on the presence of noise. The receiver should achieve the constant false alarm rate (CFAR) and the maximum probability of the target detection.

Improved Adaptive Constant False Alarm Rate Detector Based on Fuzzy Theory for Multiple-Target Scenario

Applied Sciences
An improved adaptive constant false alarm rate (CFAR) detector based on fuzzy theory is proposed to address the issue of poor detection performance and robustness of the variability index (VI) class CFAR detectors due to the misjudgment of the background
