Constant False Alarm Rate Detection of Multicarrier Signals With Periodic Power Boosting
IEEE Transactions on Cognitive Communications and Networking, 2018Given the prevalence of multicarrier waveforms in wireless systems, the sensing of such signals is of high importance for cognitive radio applications. In this paper, we exploit periodic power boosting of subcarriers in multicarrier signals which is applied, e.g., in LTE to improve the performance of sensing compared to state-of-the-art schemes under ...

Low-Loss Almost Constant False-Alarm Rate Processors
IEEE Transactions on Aerospace and Electronic Systems, 1979Conventional normalizing constant false-alarm rate (CFAR) circuits use the same configurations when detecting targets in interference regions and in clear regions. The CFAR penalty incurred in the clear region can be reduced by using CFAR processors that recognize the region is clear so that normalization is not necessary.

Constant-False-Alarm-Rate Processors for Locally Nonstationary Clutter
IEEE Transactions on Aerospace and Electronic Systems, 1973A technique for designing normalizing processors for locally non-stationary clutter is discussed. The design procedure assumes the logarithm of the clutter power varies as a polynomial with range. When the actual environment matches the design environment, the false-alarm rate is a constant that is independent of the polynomial coefficients.

Signature adaptive target detection and threshold selection for constant false alarm rate
Journal of Electronic Imaging, 2005A constant false alarm rate (CFAR) detection algorithm and a threshold selection algorithm are adapted and developed for use in multiband-image small-target detection. While it is often difficult to predict the spectral signatures of targets, the shape of the target may be known.
