| 摘 要： | 在ISAR成像中,当完成了运动目标的平动补偿后,还需进行转动补偿。本文就目标作匀速直线运动时相对雷达的转角变化进行了分析,得出在小转角条件下,该类运动的转角变化规律主要取决于非线性度因子,本文提出采用最小熵准则对进行最优估计和补偿。仿真和实测数据的计算结果表明了理论分析的正确性和补偿方法的可行性。

| Abstract: | After translational motion compensation, rotational motion compensation is needed in ISAR technique. This paper considers the rotational motion compensation in the case of that the target moves along a straight trajectory with constant speed. It is found out that the nonlinear factor 7 is most important parameter in its rotational motion compensation. In order to estimate 7, image entropy minimization principle is described here. Based on this principle, the unknown 7 can be estimated accurately. The effectiveness of this method are shown by simulated and experimental results. |
