Second-order cross ambiguity function based on the fractional Fourier transform (CAF-FRFT-SOS) can be used in joint estimation of time delay, Doppler shift and Doppler rate of the echoes, but it can not restrain the correlated Gaussian noise. This paper presents the fourth-order ambiguity function based on the fractional Fourier transform (FRFT). It can be utilized to overcome the deficiency of CAF-FRFT-SOS and be used in the unknown correlated Gaussian noise environment. The simulations prove the efficiency of this algorithm
