Chirp z transform

WebThe chirp z -transform is the z -transform of x along a spiral contour defined by w and a. m is a scalar that specifies the length of the transform, w is the ratio between points along the z -plane spiral contour of interest, and scalar a is the complex starting point on that contour. The contour, a spiral or "chirp" in the z -plane, is given by WebUsing the estimated motion errors, two-dimensional (2D) mapping is implemented to decouple the spatially variant residual into two linear independent directions so that the chirp-z transform (CZT) can be performed on the received echo data to remove the spatially variant errors.
