Estimating the time of arrival (TOA), pulse width (PW), and repetition interval (PRI) is critical for identifying low probability intercept (LPI) radar signals as it common in electronic warfare (EW) to experience a train being received. To determine these parameters, we need differentiate between noise train. However, separating LPI into challenging owing its characteristics modulation scheme....

We test the presence of a change of slope in a logistic regression model with covariate measured with errors. Under the null hypothesis of no change-point, estimation of a single intercept and slope can be carried out straightforwardly by various conditional score based methods. If the alternative hypothesis holds and indeed there exists a change-point, estimation becomes more challenging, neve...
