摘要：

Firstly, high dynamic Doppler parameters are expressed with Taylor series. Then, the relationship of Doppler frequency shift, the first order derivative and the second order derivative with the phase difference of adjacent data samples is deduced after signal nonlinear transform. Finally, an equation set is constructed and Doppler parameters are blindly estimated by solving the equations without any prior knowledge. Simulation results validate the method's feasibility and availability for commonly used satellite communication signals, such as M-ary phase shift keying (MPSK), M-ary quadrature amplitude modulation (MQAM) and so on.
