Witryna9 lis 2024 · This section now introduces a trimmed geometric mean order statistic (TM) CFAR for operation in Pareto Type I clutter. A similar detector, for the case of target detection in exponentially distributed clutter, was first examined in [].Throughout the following the choice of \(h(Z_1, Z_2, \ldots , Z_N) = Z_{(1)}\) is only considered. This … WitrynaIn contrast to all previous CFARs, order statistic CFAR (OS-CFAR) uses the ordered data in the reference window to determine Z. More specifically, if the ordered reference cells are: ... The CFAR method also can be different, but we found smallest-of cell-averaging CFAR (SOCA-CFAR) has better performance than cell-averaging, greatest …

WitrynaFrom a signal processing perspective, CFAR is shown to be a finite impulse response band-pass filter. From a statistical pattern recognition perspective, CFAR is shown to be a suboptimal one-class classifier: a Euclidean distance classifier and a quadratic discriminant with a missing term for one-parameter and two-parameter CFAR, … WitrynaThis process impairs the performance of the statistics-based detector due to contamination with abnormal data in the background statistics, improper modeling of the Gaussian distribution, and the usage of lower-order information. Many improved RX algorithms have been proposed to address these problems [20,21,22,23,24,25,26].

WitrynaConstant 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 when the cell under test exceeds the threshold. In most simple CFAR detection schemes, the threshold level is calculated by estimating the noise floor level around the cell ...
