| 摘 要： | 建立了双站ISAR运动目标的几何模型,给出了双站步进频率雷达运动目标的回波信号模型,讨论了目标运动对步进频率双站ISAR成像的影响;为补偿目标因等效径向速度引起合成距离像峰值的时移和能量发散,提出了用距离微分法估计目标的等效径向速度作粗补偿,然后用积累相关法作精补偿的成像方法;仿真结果验证了该方法的有效性。

| Abstract: | The geometry model of the bistatic ISAR for moving target was established.The echo signal model of stepped frequency bistatic ISAR for moving target was presented and the influence of the moving target speed on bistatic ISAR imaging was discussed.In order to compensate the peak shift and energy divergence of the synthesized range profiles because of the target's equivalent radial velocity,an imaging method based on the range differential coefficient and accumulation correlation was proposed.Rough compensati... |
