Abstract

This paper proposes a scheme of multiple-input and multiple (MIMO) synthetic aperture radar (SAR) for ground moving targets detection. The proposed approach employs MIMO configuration with multiple antennas in azimuth and orthogonal waveform diversity. After cancelling the clutter and estimating the along-track velocity of the moving targets with the proposed double-interferometry processing technique and estimating the Doppler parameters of the moving targets with a simplified fractional Fourier transform (SFrFT) algorithm, ground moving targets detection can then be obtained by jointly processing algorithm.
