  • Signals with sinusoid modulated phase is the general form of micro-Doppler signals in radar echoes from targets with micro-motions. This paper derives the cycle spectra of this signal using its cyclostationary character, and estimates the parameters of the signal from the cycle spectra. Compared with conventional spectra analysis methods, this parameter estimation method based on cyclostationary spectra can suppress stationary noise more effectively. Finally, the theoretic deduction and the error curves by simulations prove the validity of the process.
