description: The subject of the graduate qualification work is a monopulse active phased array (AFAR) with discrete phasing. The aim of the work is to evaluate the accuracy and effectiveness of the monopulse method in AFAR using discrete phasing. The study was conducted by mathematical modeling. The novelty and relevance of this work lies in the development and testing of a system for mathematical modeling of the operation of a radar station (radar), taking into account the imperfection of the amplitude-phase distribution (AFR) and the directional pattern control system (DN) of the antenna, as well as the statistical properties of the target and antenna noise. The WRC presents graphs showing the results of modeling, namely, an assessment of the effect of the bit depth of the phase shifters on the accuracy of determining the angular coordinates of the target by the monopulse method. There are also descriptions of modeling parameters and initial modeling conditions. The terminological features of the subject area are taken into account and software tools are used to solve problems. The specialized Matlab software has been applied.
