    Abstract

    In the detection and study of ionosphere, the instantaneous Doppler frequency can indicate the changes that the Doppler effect changes over time, to reflect the change law of ionosphere. Using the two instantaneous frequency estimation methods of the phase difference and phase modeling, the echo signal for actual ionospheric oblique backscattering sounding system is simulated and analyzed. The results show that the phase modeling can more accurately reflect the change law of the ionosphere.
