WitrynaThe order statistic CFAR (OS-CFAR) is designed to overcome the above problem arisen in CA-CFAR. OS-CFAR has a significant advantage when detecting targets in multiple target situations, but the optimal statistic is obtained by experience and the computational efficiency is quite low. Witryna25 lis 2024 · According to the order of the scores, a certain proportion of polymer image points are considered as outer points, which are the defect sub-images. This method completely relies on statistical strategy to make use of the periodic texture characteristics of the image, and can detect the non-lattice texture image without …

Witryna20 wrz 2024 · The CFAR detects ships by finding a threshold value using the probability density function (PDF) of background clutter [8,9,10,11]. However, detection results from the CFAR algorithm can be biased by statistical variables such as mean and standard deviation, because the false-alarm rate must be fixed .

WitrynaExperiments were performed for different scenarios of multiple targets using various movements. It is verified that the proposed algorithm has improved performance in terms of both detection rate and false alarm rate compared with conventional approaches, such as cell averaging CFAR and ordered statistics CFAR. 더보기 취소 Witryna25 sie 2024 · High-frequency surface wave radar (HFSWR) is an important marine monitoring technology, and this new regime of radar plays an important role in large-scale, continuous early-warning monitoring at sea.

Witryna1 lut 1995 · Order-statistics (OS) is a constant false alarm rate (CFAR) technique which is relatively immune to the presence of interfering targets among the reference cells … WitrynaThe results show that the frequency spectrum of the real sea clutter is fractal in the statistical sense and the frequency Hurst exponents of clutter range bins and target range bins are distinguishable. Therefore the frequency Hurst exponent is used for the CFAR target detection within sea clutter. ... Order statistics CFAR for Weibull ...

WitrynaIn order to achieve full CFAR, in the Pareto Type II case, a novel Bayesian methodology is introduced. This approach is general and can be extended to other distributional settings. In the first instance, the Bayesian approach is outlined for single parameter clutter models, and then specialised to the exponentially distributed clutter setting ... WitrynaThe detection of this class has many practical applications. Structure of the CA GTM detector is described briefly. Detection performances for optimal, CA TM, CA, trimmed-mean (TM) and ordered-statistic (OS) CFAR strategies have been analyzed and compared for desired probability of false alarm and determined size of the reference …

WitrynaIn order to reduce computational complexity, an aggregate model of PEVs is provided using statistical data. In the end, the performance of PEVs for the provision of PFC is evaluated in a power system. Results show that PEV fleets can successfully improve frequency response, once all the operating constraints are respected. Mostrar menos WitrynaFor more accurate operation in multi-target environments, the Order Statistic (OS)-CFAR processor has also been presented. ere, the noise power estimation is based on the H ion of the Kselect th largest cell in a reference sliding window of size N [12]. Minimal loss is thus achieved when the K = 3 4 N, and the probability of detection, …
