Abstract
The envelope correlation algorithm is widely used in range alignment of ISAR motion compensation, however, this method often make the error accumulation, and what is more, a jump error will make when the reflection of target has strong scintillation. To reduce the error of range alignment a minimum entropy criterion of range alignment in ISAR compensation is proposed. Using this method the range bin can be alignment correctly which is verified by real radar data
