The article presents the results of the development of an algorithm for forming a topology of a radio network using ultra-wideband radio stations, including trunk radio links, communication lines with aircraft and radio links between mobile subscribers. The input data are the initial structure of the control system, the composition of the management directions and the communication nodes included in them and the positions of their location on the ground. The generated structure is a set of relationships between radio stations and communication nodes for a given location area, subscriber locations, communication channels assigned to radio stations in a given area, for radio communication lines of various types - trunk radio links, communication lines with aircraft and radio links between mobile subscribers, in low-range networks. The developed algorithm is based on the solution of subtasks: distribution of working frequencies; determining the possibility of organizing connections between radio stations and constructing communication matrices of radio stations and communication nodes.

To calculate frequency-energy characteristics for estimating the communication range between subscribers, analytical relations of the theory of radio wave propagation for ultra-short-pulse radiation have been developed, which differ from those known in that when calculating the received signal power in the radio communication equation, the possibility of not fulfilling the condition on relative narrow-band signals is taken into account, and antenna characteristics such as the directional action factor of the transmitting antenna and the effective area of the receiving antenna are presented in integral form. In an analytical form, an energy transmission-reception equation of ultra-wideband signals is obtained, which allows evaluating the possibility of communication between radio stations as a function of communication range, signal-to-noise ratio and sensitivity.

The developed algorithm can be used to generate initial data on the structure of ultra-wideband radio communication networks during the study of their functioning - evaluation of speed characteristics, algorithms for transmitting information, estimation of connectivity, to recalculate relationships during movement of subscribers or destructive effects on them, when subscribers work in networks of various scales.
