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.
