WebJan 1, 2024 · For K-distributed clutter, the α-MF detector is an effective detector which minimizes the loss relative to the optimum one and can be implemented fast and in real time. Similar to the OKD in K-distributed clutter, the high computational cost of the Bessel function restricts the practical application of the GLRT-IG detector in radar systems. 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 … fyoder dazai locekd together https://dacsba.com

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.
