Performance of Distributed CFAR Processors in Pearson Distributed Clutter
This paper deals with the distributed constant false alarm rate (CFAR) radar detection of targets embedded in heavy-tailed Pearson distributed clutter. In particular, we extend the results obtained for the cell averaging (CA), order statistics (OS), and censored mean level CMLD CFAR processors operating in positive alpha-stable (P&S) random variables to more general situations, specifically to ...
متن کاملPerformance Analysis of Some New CFAR Detectors under Clutter
In order to improve the radar’s detection performance under Pearson distributed background clutter, the problem of designing CFAR detectors is studied in this paper. Three kinds of distributed fuzzy CA scheme and two kinds of OS scheme are proposed. The numerical simulations prove that CA CFAR detector based on algebraic sum fusion rule provides more robust detection performance in homogenous b...
متن کاملPerformance Analysis of a Modified Cfar Based Radar Detector under Pearson Distributed Clutter
An adaptive target detector in radar system is used to extract targets from background in noisy environment of unknown statistics. The constant false alarm rate (CFAR) is well known detection algorithm that is being used in almost every modern radar. The cell averaging CFAR is the optimum detector in homogeneous clutter environment when the refence cells have identically independent and exponen...
متن کاملAdaptive CFAR Detection for Clutter-Edge Heterogeneity Using Bayesian Inference
Reliable radar constant false alarm rate (CFAR) detection is critical in dynamic clutter and jamming scenarios [2]. The existence of heterogeneities in practical operational environments renders the conventional cell averaging CFAR (CA-CFAR) ineffective. Heterogeneities arise due to the presence of multiple targets and clutter edges [3]. Alternative schemes have been developed to address this i...
متن کاملMultistatic adaptive CFAR detection in non-Gaussian clutter
This work addresses the problem of target detection for multistatic radars. We propose an algorithm that is able to keep constant the false alarm rate, when the disturbance samples associated with each receiver-transmitter pair are distributed according to a compound Gaussian model. The performance of the proposed detection algorithm are analysed to assess the impact of clutter diversity on det...
