Abstract :
The translation created by the maneuvering target has effect on image quality according to ISAR imaging. The traditional solution is to use complex motion compensation technology to eliminate the motion component. The MIMO radar system proposed in recent years also can use ISAR imaging algorithm to distinguish targets with its multi-channel observation characteristics and the reasonable configuration of transceiver array. The transmitter emits a series of orthogonal linear frequency modulation signals. So phase compensation and data rearrangement need to be done to maintain phase history. This method effectively reduces the imaging time and makes a good two-dimension ISAR image. So it can reduce influence of the target translation component to image quality. The simulation experiment obtains multiple scatters of rotation target image, and the experiment results have verified the effectiveness of the method.
