Compressive CFAR Radar Processing
In this paper we investigate the performance of a combined Compressive Sensing (CS) Constant False Alarm Rate (CFAR) radar processor under different interference scenarios using both the Cell Averaging (CA) and Order Statistic (OS) CFAR detectors. Using the properties of the Complex Approximate Message Passing (CAMP) algorithm, we demonstrate that the behavior of the CFAR processor is independe...

متن کاملInfluence of ordered and weighted analysis windows on detection in a CFAR radar
In this paper, we propose a novel algorithm for a CFAR radar detector. The proposed processor is derivated from OS CFAR one and is based on weighting samples taken for the background level estimate. We assume that targets are embedded in a Gaussian noise and fluctuate according to Swerling I model. First, closed form expressions of the probabilities of detection and false alarm are determined a...
متن کاملPerformance Analysis of CFAR Detection of Fluctuating Radar Targets in Nonideal Operating Environments
A constant false alarm rate in the presence of variable levels of noise is usually a requirement placed on any modern radar. The CAand OS-CFAR detectors are the most widely used ones in the CFAR world . The cell-averaging (CA) is the optimum CFAR detector in terms of detection probability in homogeneous background when the reference cells have identical, independent and exponentially distribute...
متن کاملFormulation of a generalised switching CFAR with application to X-band maritime surveillance radar
A generalisation of a switching based detector is examined, allowing the construction of such detectors for target detection in any clutter model of interest. Such detectors are important in radar signal processing because they are robust solutions to the management of interference. Although formulated in general terms, the theory is applied to the design of a switching constant false alarm rat...
