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.

Keywords: frequency band, radar system, electromagnetic pulse, detection (recognition) of an object radar signal processing, numerical model, software, algorithms.
