与平面目标相比,舰船目标的逆合成孔径雷达(ISAR)成像具有重要意义,由于舰船运动的复杂性,使得舰船目标的成像条件比平面目标复杂。本文将舰船目标接收信号建模为多分量三次相位信号,提出了利用乘积高阶匹配相位变换估计各分量参数的方法。然后,可以获得瞬时ISAR图像。通过对真实的数据的处理,验证了该方法的有效性。
Inverse synthetic aperture radar (ISAR) imaging of a ship target is very important compared with the plane target, and the imaging condition of the ship target is more complicated than that of the plane target due to the complexity of the ship's movement. In this letter, the received signal of a ship target is modeled as a multicomponent cubic phase signal, and the product high-order matched-phase transform is proposed to estimate the parameters of each component. Then, the instantaneous ISAR images can be obtained. Results of real data demonstrate the effectiveness of the new method proposed.
