The inverse synthetic aperture radar (ISAR) echo signal model of fast-moving target and the effect of target fast-moving on ISAR signal processing were analyzed.

分析了高速运动目标的逆合成孔径雷达（ISAR）回波信号模型和目标高速运动对ISAR信号处理的影响。

So, it requests radar provided with the ability to restrain clutter wave for differentiating the echo of moving target.

因此要求雷达必须具备很强的抑制杂波的能力，能在较强的杂波背景中分辨出运动目标的回波。

In high range resolution conditions, the migration of moving target causes the migration of echo envelop within multicycle integration time and brings the decline of detection performance.

在高分辨条件下，多周期积累时间内目标的运动会造成回波包络的跨单元走动，而距离走动带来了检测性能的下降。
