Abstract

A large increase in terahertz radar resolution under large bandwidth condition is particularly important for one-dimensional distance projection method to obtain more extensive information about the target feature. This chapter presents the details of a terahertz radar echo data model in terms of the geometrid theory of diffraction concept. The MUSIC spectral estimation algorithm in the implementation process is discussed. Finally, the MUSIC spectral estimation algorithm from the estimated scattering center projections and at different signal-to-noise ratios is simulated. The results obtained exhibited high precision, and noise immunity was better, which proves the effectiveness of the spectral estimation using MUSIC algorithm.
