DL-CFAR: A Novel CFAR Target Detection Method Based on Deep Learning
2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), 2019The well-known cell-averaging constant false alarm rate (CA-CFAR) scheme and its variants suffer from masking effect in multi-target scenarios. Although order-statistic CFAR (OS-CFAR) scheme performs well in such scenarios, it is compromised with high computational complexity. To handle masking effects with a lower computational cost, in this paper, we

CFAR strategies for channelized radiometer
IEEE Signal Processing Letters, 2005The channelized radiometer is a well-known intercept receiver. We analyze its performance when different constant false alarm rate (CFAR) strategies are used to set a detection threshold based on values of some reference cells. The studied conventional methods are cell-averaging (CA) and order statistics.

CFAR Detectors for MIMO Radars
Circuits, Systems, and Signal Processing, 2012CFAR (Constant False-Alarm Rate) processors are useful for detecting radar targets in a background for which the parameters in the statistical distribution are not known. A variety of CFAR techniques such as CA (Cell Averaging), Go (Greatest Of), SO (Smallest Of), OS (Ordered Statistics) and ACMLD (Automatic Censored Mean-Level Detector) processors ...

Analysis of a CFAR correlation radiometer
2015 International Conference on Military Communications and Information Systems (ICMCIS), 2015The two antenna correlation radiometer is used detecting unknown signals but its principle equals a single antenna detector where a signal is correlated by its delayed version. Its performance, its sensitivity to errors in noise power estimation as well as its constant false alarm rate (CFAR) form have been analyzed previously.

Asymptotically Optimal CFAR Detectors
IEEE Transactions on Signal Processing, 2015This paper investigates the asymptotic optimality of the Constant False Alarm Rate (CFAR) tests obtained using the Minimal Invariant Group (MIG) reduction. We show that the CFAR tests obtained after MIG reduction using the Wald test is a Separating Function Estimation Test (SFET) and that the Generalized Likelihood Ratio Test (GLRT) and the Rao test ...

Robust Distributed Sonar CFAR Detection Based on Modified VI-CFAR Detector
2019 International Conference on Control, Automation and Information Sciences (ICCAIS), 2019This paper proposes a robust distributed constant false alarm ratio (CFAR) detection algorithm to deal with the multistatic sonar target detection problem in the heterogeneous underwater environment. The local detector in the distributed sonar network employs the modified variability index (VI) CFAR where we apply the automatic censored mean level ...

In automatic target detection radars, adaptive constant false alarm rate (CFAR) processors, which determine the threshold, are examined. Two techniques are used for achieving the required CFAR. The first technique determines the adaptive threshold using range neighbouring cells which are located in sliding window. The second one is based on clutter map.
