In this paper, a range migration algorithm for single-input multiple-output array imaging is presented. Similar to the range migration algorithm in synthetic aperture radar imaging, the proposed method first transforms the measurement data into the wavenumber domain to interpolate. Due to the multistatic configuration, the interpolation used here is different to that in synthetic aperture radar. After interpolation, the imaging result is obtained by accumulation and inverse Fourier transform. Since the curvature of the wavefront is completely compensated and the Fourier transform based imaging scheme is utilized, the method can be applied under the near-field condition and has high imaging efficiency. The experiment data validate its performance.
