WebA CFAR detection occurs when the input signal level in a cell exceeds the threshold level. The threshold level for each cell depends on the threshold factor and the noise power in that derived from training cells. To maintain a constant false alarm rate, the detection threshold will increase or decrease in proportion to the noise power in the ...

WebAug 27, 2015 · $\begingroup$ Actually, having two separate threshold values is exactly the same: the hysteresis method is based on applying two separate threshold values for the 'on' and 'off' events. If you observe the signals 'live' in a y/t viewer or plot, it is sometimes clearer to see only one threshold line (which changes with each event) instead of having two lines.
