WebCell-Averaging CFAR Detector. The cell-averaging CFAR detector estimates the noise variance for the range cell of interest, or cell under test, by analyzing data from neighboring range cells designated as training cells.The noise characteristics in the training cells are assumed to be identical to the noise characteristics in the cell under test (CUT). 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 …

WebMar 15, 2016 · where \(\alpha\) is the threshold factor, \(P_n\) stands for the noise power of training cells, \(N\) is the number of training cells and \(P_{fa}\) means the false alarm rate.. Form the equations above, we can observe that lower false alarm rate will lead to higher threshold level. Code example. This example demonstrates how to implement cell … WebThe exponential noise model was used for clear and clutter backgrounds to get closed-form expressions. The processor types compared are: the cell-averaging CFAR, the 'greatest of' CFAR, the 'smallest of' CFAR, the ordered-statistics CFAR, and a modified ordered-statistics processor called the trimmed-mean CFAR.< >

WebConstant False Alarm Rate (CFAR). The center is the cell under test. The two adjacent cells are added and multiplied by a constant to establish a threshold. Detection occurs … WebRadar detection procedures involve the comparison of the received signal amplitude to a threshold. In order to obtain a constant false-alarm rate (CFAR), an adaptive threshold must be applied reflecting the local clutter situation. The cell averaging approach, for example, is an adaptive procedure. A CFAR method is discussed using as the CFAR …
