- Range alignment is crucial in motion compensation of the inverse synthetic aperture radar (ISAR). 摘要距离对准是逆合成孔径雷达(ISAR)运动补偿的关键。
- Motion compensation,which usually includes range alignment and phase compensation,plays a key role in ISAR imaging. 运动补偿是ISAR成像中的关键技术,通常包括包络对齐和相位补偿,而包络对齐是相位补偿的基础。
- Due to their low accuracy or low efficiency, the conventional range alignment algorithms can't satisfy the requirements of real-time ISAR imaging. 传统的距高对齐算法或对齐精度不够高,或运算效率过低,无法满足ISAR实时成像的要求。
- Results show that the range alignment algorithm based on maximum modified kurtosis can estimate range shifts and fulfills range alignment. 结果表明,基于最大修正峰度的距离对准算法可以准确地估计出回波的距离偏移量,实现距离对准。
- Translation compensation consists of range alignment, which aligns the signals from the same scatterer in range, and phase adjustment, which removes the translational Doppler phase. 距离对准是要将同一散射点在各个不同回波中的样值对准到同一距离门中,相位校正是要将雷达和目标之间的平动多普勒相位从各个回波中移除。
