Abstract. The
possibilities of a computer simulation of radar systems in terahertz (THz)
range as the development of numerical models, software and algorithmic support,
are investigated. The propagation of electromagnetic pulses in waveguides with
finite wall conductivity and the diffraction of electromagnetic pulses on
objects with the dispersion of dielectric permittivity are also analyzed. The
mathematical model of the devices design for primary processing in modern THz
radars, confirming chosen circuit solutions and achieving their desired
characteristics, is considered. The complex algorithms are proposed for optimal
processing of radar THz range signals to solve problems of detection and
recognition of physical objects.
