WebAug 2, 2016 · Abstract: In this paper, we address the problem of detecting fluctuating targets in heavy-tailed clutter through the use of dynamic programming based track-before-detect (DP-TBD) in radar systems. The clutter is modeled in terms of K distribution, while the well-known Swerling targets of types 1 and 3 are considered to capture the target … WebThe detection performance of a cell-averaging CFAR detector is analysed for spatially correlated K-distributed clutter. In thermal noise or uniform clutter, the performance of the cell-averaging CFAR can be compared with that of the ideal fixed threshold, but with an associated ‘CFAR loss’, quantified by the increase in average signal-to-clutter ratio … WebMay 10, 2024 · Learn more about clutter, sea clutter, k distribution, log distribution, statistics, signal processing Phased Array System Toolbox.

WebHowever, in most fielded systems, unwanted clutter and interference sources mean that the noise level changes both spatially and temporally. In this case, a changing threshold can be used, where the threshold level is raised and lowered to maintain a constant probability of false alarm. This is known as constant false alarm rate (CFAR) detection.
