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. [2]. 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. [2] 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.
