In this paper, a 0.32 THz imaging radar system was built and experiment on a precession warhead model is presented. The imaging algorithm based on range-instantaneous Doppler algorithm is adopted and high resolution ISAR imaging results are obtained. From these imaging results, we can easily recognize structures and even the subtle structures of the precession target, which verify the advantages of terahertz radar in high resolution imaging.
