摘要

A previous work proposed 3 time efficient sampling schemes for 3-D inverse synthetic aperture radar (ISAR) imaging, yet the dynamic range of these schemes is less than 10dB. In order to enlarge imaging dynamic range, a target recovery method based on compressed sensing (CS) is used instead of matched filtering. The dynamic range of point spread function (PSF) based on the new method is more than 60dB, a target with a 30dB RCS range can be perfectly reconstructed. With efficient sampling schemes and CS imaging method, both time efficiency and imaging performance can be achieved.
