WebSignal Detection Using Longer Waveform. As discussed in the previous example, the threshold is determined based on Pfa. Therefore, as long as the threshold is chosen, the … Webnpwgnthresh enables you to specify the maximum false-alarm probability as a constraint. A false alarm means determining that the data consists of a signal plus noise, when only noise is present. For details about the statistical assumptions the npwgnthresh function makes, see the reference page for that function.

WebThe resulting false alarm rate can then be calculated based on the number of false alarms and the number of trials. x_detected = cfar (x,CUTIdx); act_pfa = sum (x_detected)/Ntrials. act_pfa = 9.4000e-04. The result shows that the resulting probability of false alarm is below 0.001, just as we specified. Webnpwgnthresh; On this page; Syntax; Description; Examples.

WebFirst, detections are generated using a statistical model based on the radar equation. Next, an equivalent physics-based radar model is created from the statistical model. The physics-based radar model is then used to simulate the IQ signal and generate the detections. The example shows that the detections from the two models are consistent. inland rail completion dateWebPulsed Radar Systems.
