Abstract

Abstract

The cross-range scaling is the base of the pattern matching and target characteristic extraction. Using the approximately proportional relation between the Doppler frequency in cross range and the transverse coordinate position, and based on the orthogonal relation between the centerline and the line through axially symmetric points in the symmetrical target, a novel method of rotation angle estimation and cross range calibration is given for the symmetrical target. Then, the estimation error expression of the scaling parameter is offered, and influencing factors of the parameter estimation error is analyzed quantitatively. Finally, the ISAR imaging simulation results of both the warhead model on rotating platform and the outfield airplane data verify this method. This method has a very good application prospect to the ISAR image calibration aspect of cooperative maneuvering target with simple and low computation cost.
