Abstract

Presents a new processing algorithm for spotlight SAR data. The spotlight mode offers the potential of achieving very high geometric resolution. The extended chirp scaling (ECS) processing performs a subaperture approach combined with azimuth scaling and a new frequency scaling for range cell migration correction (RCMC). The subaperture processing and the effect of the frequency scaling are discussed. Simulation results demonstrate the precision processing in high resolution mode.
