Investigates periodogram-like estimates in chirp signals, suggesting robust statistical properties.
A time continuous model of the simplest chirp signal observed against the background of strongly or weakly dependent stationary Gaussian noise is considered. For the specified statistical model, strong consistency and asymptotic normality of periodogram-like estimates of unknown amplitude, angular frequency, and chirp rate are obtained.
