Abstract

High speed movement of target leads to quadratic phase of the dechirped signal. A new high speed movement compensation method based on integrated cubic phase function is proposed. Numerical result shows that the algorithm can precisely estimate the quadratic phase coefficient and compensate the high resolution range profile under low signal to noise ratio. After compensation, the aberration of range profile is revised and the quality of ISAR image is greatly improved. In this way, the effectiveness of the method is verified.
