Range Migration Correction with Keystone Transform Using P-CHIP Interpolator

In this paper, keystone transform with a P-chip interpolator is used to improve ambiguity resolution and for compensating linear range migration. These non-idealities are caused by high radial velocities in ultra-wideband synthetic aperture radar applications. For increased efficiency, P-chip interpolator is used to re-sample the slow time data of the radar data matrix. The adopted sequence involves generation of signal model followed by Keystone transform with the proposed interpolation technique. Some numerical results from simulations have been presented with reference to a wide-band signal in a radar dataset.
