Estimation of parameters in random amplitude chirp signal
In this paper, we consider the random amplitude chirp signal model observed with independent and identically distributed additive error as proposed by Besson et al. . The random amplitudes are also independent and identically distributed random variables with non-zero mean and some finite higher order moments. We consider the estimators proposed by Besson et al.  and study their theoretical properties. It is observed that the estimators are strongly consistent and asymptotically normally distributed. We propose a new multi-component random amplitude chirp model, which can be more useful in practice. Numerical experiments are conducted to see the small sample performances.
