逆合成孔径雷达(ISAR),由于其良好的空间分辨能力,非常适合于空间目标的探测研究。它通过采用宽带信号来获得高距离分辨能力,通过对目标不同方向上接收回波进行相干处理来获得精细的横向距离(方位)分辨能力。这种雷达得到的高分辨二维图像提供了更好的目标特征探测性能。文中给出了一种用于空间目标逆合成孔径成像的实验研究。

Inverse Synthetic Aperture Radar(ISAR) is propitious to detect the space targets for its advantages in the space resolution.ISAR can acquire high resolution range profile by adopting wide bandwidth signal,and simultaneously,it can obtain the refined cross-range by the coherent accumulation of the different rotating angle echoes of the target.The high resolution of the two-dimension image acquired by ISAR can provide better characteristics of the target.In this paper,an experimental reserach of ISAR system is proposed to image the space target.
