Simulation of ISAR imaging of launch vehicle in boost phase

Abstract

The simulation of Inverse Synthetic Aperture Radar (ISAR) imaging of the launch vehicle in boost phase is described in this paper. Different from traditional target, the motion of the one studied in this simulation is characterized by both high radial velocity and non-uniform rotating, which will defocus the image in both the range and cross-range dimension. Range and azimuth compression methods employing FRFT are used to refocus the image. A typical example is exhibited to show the performance of the simulation.
