N2 - To solve the problem of cross-range scaling of noncooperative target ISAR imaging, a corresponding analysis method is proposed based on phase frequency modulation parameter estimation. Doppler expression of the echo is deduced and the demodulation frequency method is used to estimate the parameters of the LFM signal, and then estimation of the frequency response of the echo signal in the longitudinal distance unit can be obtained. Finally, the slope of the echo signal is calculated by linear fitting. The radar echo data can be calculated to obtain the imaging target rotation speed of the estimated value. Simulation results compared with other classic methods confirm the feasibility and timeliness of the algorithm.
