Modified reference window for two-dimensional CFAR in radar target detection
The Journal of Engineering, 2019 The constant false alarm rate (CFAR) technology plays an important role in radar target detection. In cell averaging CFAR detectors, a reference window is usually adopted to estimate the average interference power in the range–Doppler matrix and to ...

An Improved Bilateral CFAR Ship Detection Algorithm for SAR Image in Complex Environment
Leida xuebao, 2021 The Bilateral Constant False Alarm Rate (BCFAR) detection algorithm calculates the spatial information of Synthetic Aperture Radar (SAR) image by the Gaussian kernel density estimator, and combines it with the intensity information of image to obtain the

Robust Control for the Detection Threshold of CFAR Process in Cluttered Environments
Sensors, 2020 The constant false alarm rate (CFAR) process is essential for target detection in radar systems. Although the detection performance of the CFAR process is normally guaranteed in noise-limited environments, it may be dramatically degraded in clutter ...

Acoustic tamper detection sensor with very low false alarm rate [PDF]
, 2008 We describe a device designed to detect interference (vandalism or tampering) by acoustic means. The design employs both a piezoelectric vibration transducer and a common microphone in a novel mechanical arrangement.

CFAR Detection from Noncoherent Radar Echoes Using Bayesian Theory
EURASIP Journal on Advances in Signal Processing, 2010 We propose a new constant false alarm rate (CFAR) detection method from noncoherent radar echoes, considering heterogeneous sea clutter. It applies the Bayesian theory for adaptive estimation of the local clutter statistical distribution in the cell ...

CFARnet: deep learning for target detection with constant false alarm rate [PDF]
, 2023 We consider the problem of target detection with a constant false alarm rate (CFAR). This constraint is crucial in many practical applications and is a standard requirement in classical composite hypothesis testing. In settings where classical approaches
