Compressive Cyclostationary Spectrum Sensing with a Constant False Alarm Rate
Correspondence: [email protected] 1 Institute for Theoretical Information Technology, RWTH Aachen University, Kopernikusstraße 16, 52074, Aachen, Germany Full list of author information is available at the end of the article Abstract Spectrum sensing is a crucial component of opportunistic spectrum access schemes, which aim at improving spectrum utilization by allowing for the reuse of i...
متن کاملCompressive Wideband Spectrum Sensing based on Cyclostationary Detection
Cognitive Radios (CRs) operating in a wideband channel must detect the presence of licensed users within a constrained sensing time, and under energy limitations. In this paper, we explore a reduced-complexity compressive sampling cyclostationary detection method which exploits the sparsity of the two-dimensional spectral correlation function (SCF). We obtain a closed-form expression that recon...
متن کاملSignature Adaptive Mine Detection at a Constant False Alarm Rate
A constant false alarm rate (CFAR) 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 general statistical model of the da...
متن کاملExpert System Application to Constant False Alarm Rate (cfar) Processor
An artificial intelligence system improves radar signal processor performance by increasing target probability of detection and reducing probability of false alarm in a severe radar clutter environment. This utilizes advances in artificial intelligence and expert systems technology for the development of data analysis and information (signal) processors used in conjunction with conventional (de...
متن کاملConstant False Alarm Rate Detectors in Intensive Noise Environment Conditions
A different technique of CFAR detectors procedure for moving target detection in noise environment conditions with a Poisson distributed flow and Raleigh amplitude distribution is proposed in this paper . The expressions of the detection and false alarm probability are derived for a highly fluctuating Swerling II target. A comparative analysis of the performance of different radar detectors str...
