Abstract. The problem of improving the accuracy and speed of measurement of angular coordinates in monopulse radar system overview with a total amplitude-difference meter is worked out. Based on these studies, as well as the optimization of a computer model taking into account the possibilities of modern methods of digital signal processing, a method of signal processing is elaborated, the last one provides reception of cubic direction-finding performance and analytical solution of the direction-finding equation with an accuracy of 1% of the width of the partial directional pattern in the working area, increased to monopulse width groups of rays. The algorithm works on the basis of the radar system antenna array, which has increased the speed and accuracy of measurement of angular coordinates. The block diagram of radar system is examined and its operating principle is described.

Key words: monopulse radar system, direction-finding feature, antenna array, radiation pattern.
