WebA constant false alarm rate (CFAR) can be obtained by adjusting the threshold in accordance with the measured background. There are different schemes for obtaining CFAR. The cell-average CFAR uses a tapped delay line to sample the range cells to either side of the test cell. The number of taps used in the cell-average CFAR might vary from 16 … WebMay 11, 2012 · Real-time implementations of ordered-statistic CFAR Abstract: Ordered-statistic constant false alarm rate (OS-CFAR) detectors provide improved robustness over cell-averaging CFAR (CA-CFAR) detectors in multiple …
