Abstract

To resolve the range migration and Doppler frequency spread, a new parameter estimation method, namely Dual-carrier frequency-Radon fractional Fourier transform (DCF-RFRFT), is proposed based on the dual-carrier frequency radar data. In this method, dual-carrier frequency radar data is constructed in the range frequency domain and a new signal is constructed by multiplying one with the complex conjugate of the other. Radon fractional Fourier transform (RFRFT) is performed to obtain the estimates of velocity and acceleration. This method does not need any prior-knowledge of targets and can resolve the Doppler ambiguity problem. The simulation results demonstrate the effectiveness of the proposed algorithm.
