Algorithm and two-phase processing mathematical model of signal in monopulse direction finding task is suggested. The initial data is pulse chips from some mutually spaced radio sources. They are registered by digital multichannel receiver with antenna array with antenna elements on the circle. In the algorithm for identifying angular coordinates we should do the following: 1. Fulfil the radio sources search and finding. 2. Evaluate the most possible radio source directions (I stage). 3. Specify radio source angular coordinates on the chosen directions (II stage). The results of mathematical modelling for 6 receiver antennas located in regular hexagon tops which adjacent antenna pattern intersects 3 dB level are in this article.
