I'd tried coding this project (prob. 3-2, third paragraph) in MATLAB through this tutorial : … Websnrthresh = npwgnthresh(pfa) calculates the Detection SNR Threshold in decibels for detecting a deterministic signal in white Gaussian noise. The detection uses the Neyman-Pearson (NP) decision rule to achieve a specified probability of false alarm, pfa.This function uses a square-law detector.

WebEstimate Range and Doppler Using Pulse Compression. This example shows the effects of pulse compression, where a transmitted pulse is modulated and correlated with the received signal. Radar and sonar systems use pulse compression to improve signal-to-noise ratio (SNR) and range resolution by shortening the duration of echoes. WebCreate a linear FM waveform with a duration of 0.1 milliseconds, a sweep bandwidth of 100 kHz, and a pulse repetition frequency of 5 kHz. Add noise to the linear FM pulse and filter the noisy signal using a matched filter. This example applies a matched filter with and without spectrum weighting. Specify the waveform. inland rail central https://artisandayspa.com

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.
