Abstract :
In the present work we consider the estimation algorithm of the appearance time of the high-frequency Gaussian random pulse with free-form envelope against white noise. Contrary to the known studies, we supposed the useful signal duration to be known inaccurately. We found the asymptotically exact analytical dependences for the conditional bias and variance of the appearance time estimate on the basis of the local Markov approximation method. Then, by the methods of statistical computer modeling, we established that the received theoretical results adequately agrees with the corresponding experimental data in a wide range of output signal-to-noise ratios.
