Abstract
A new method based on fractional correlation theory for estimating the Doppler parameters of the echoes signal is presented. Firstly, a signal array model is constructed with time-variant Doppler frequency. Secondly, one of the Doppler frequency parameters, initial Doppler frequency, is estimated by energy concentrated of multipath component based on fractional correlation transform. Then, an order-reduced signal is reconstructed combining the Doppler with the prior knowledge of the transmitted signal, and the echoes signal is converted to many single-frequency signals. Finally, the multipath time delay is obtained by the dechirping method. Simulation results are given in this paper and the results show that the new method is valid.
