Abstract :
High resolution squint synthetic aperture radar (SAR) requires the compensation of range-dependent range cell migration (RCM) and second range compression (SRC). The chirp z transform can correct RCM efficiently. Using the chirp z transform, the paper proposes an approach to solve SRC by dividing range dimensions into blocks. Simulation results demonstrate the validity of the approach
