Abstract
Novel range migration algorithm for MIMO array-based imaging is proposed. The Stolt interpolation of the range migration algorithm is replaced with nonuniform Fast Fourier Transform, which has resulted in accuracy and the computation efficiency improvement. The way to extend the proposed algorithm to 2D arrays is proposed. Numerical simulations are performed to verify the accuracy and efficiency of the algorithm.
