摘要：

This paper proposes a novel method to estimate 2FSK-LFM compound signal based on joint FRFT-ML. The representation of the compound signal in FRFT domain is derived and the chirp rate and the code length of the compound signal are estimated. Joint with ML method, a high accurate local search approach is proposed and the carrier frequencies of the compound signal are estimated. Simulation results show when SNR>5dB, our algorithm can achieve a high accurate performance and distinguish the different carrier frequencies of the compound signal.
