“…The reconstructed image is located away from the rotational center by directly using inverse Fourier, so the three-dimensional ISAR image is obtained through coherent processing of the backscatter field, which is a function of frequencies and rotation angles of the two mutually orthogonal axes [ 8 ]. The literature [ 13 ] gives a method for short-range 3-D ISAR imaging of the moving target using the interferometric ISAR technique based on a chirp signal system. Methods for imaging of energy focusing on the time domain have been widely used in the near-field [ 10 , 11 , 13 , 14 , 15 , 16 ].…”

This paper proposes a three-dimensional inverse synthetic aperture radar (ISAR) imaging method for high-speed targets in short-range using an impulse radar. According to the requirements for high-speed target measurement in short-range, this paper establishes the single-input multiple-output (SIMO) antenna array, and further proposes a missile motion parameter estimation method based on impulse radar. By analyzing the motion geometry relationship of the warhead scattering center after translational compensation, this paper derives the receiving antenna position and the time delay after translational compensation, and thus overcomes the shortcomings of conventional translational compensation methods. By analyzing the motion characteristics of the missile, this paper estimates the missile’s rotation angle and the rotation matrix by establishing a new coordinate system. Simulation results validate the performance of the proposed algorithm.
