Abstract :
Keystone transforms could correct range migration without the information about target velocity. In this paper, the principles and realizations of keystone transforms are analyzed. And keystone transforms using several interpolation methods are evaluated. It is shown that using Sine, frequency sampling, Lagrange interpolation are superior to piecewise linear and 3-spline interpolation.
