In the traditional microwave band, high accuracy parameter estimation is often hard to realize because of the poor resolution. In this paper, a high accuracy parameter estimation method of the precessing targets in the terahertz band was proposed, and an experiment based on a precessing warhead model with a 0.32 THz wideband radar system was carried out. The processing results of the real measured data prove the feasibility and precision of the proposed method, and also show the promising prospects of terahertz radar systems in future military applications.
