摘要：
A new approach to the range-independence frequency scaling (FS) factor of translational invariant bistatic synthetic aperture radar (SAR) is presented to solve the problem that the range cell movement (RCM) of bistatic SAR is influenced by transmitter and receiver range histories. The change of the RCM with two dimensional ranges is translated into that with one dimensional range, so the independent FS factor is acquired with the linear approximation of range migration. And based on this new approach, the FS algorithm is extended into translational invariant bistatic SAR. Finally, the new approach is validated by point target simulations.
