Abstract: В даній статті досліджується задача визначення відстані між прийомопередавачами хаотичних радіоімпульсів. розрахунок відстані виробляється за часом поширення сигналу в ефірі. Оцінюється точність визначення між прийомопередавачами на основі часу проходження сигналу, з урахуванням перешкод.
Now there are various technological solutions for determining the position of objects in space or on the surface of the earth. This is due to the fact that it is impossible to implement one universal method that is suitable for all possible cases. More precisely, it is impossible to make a device whose specifications would meet the requirements of all (or even most) tasks. The task of positioning is of great interest to developers and manufacturers of equipment, which can testify to its demand. Moreover, most solutions use the radio signal as a carrier of information. Consequently, universal devices that allow simultaneously to transmit and receive data, as well as determine their position in space will have a consumer value. One of the standards governing the operation of wireless transmitting devices with positioning function - IEEE 802.15.4. The general approach to determining the location of an object is based on measuring the characteristics of the radio signal emitted by the transmitter located on the object, and is taken by stationary receivers with known coordinates. According to these characteristics, the distance between the transmitter and each of the receivers is estimated. Then, taking into account the geometric principles, the coordinates of the object are determined. In this paper, the problem of determining the distance between transceivers of chaotic radio pulses is investigated. the distance calculation is based on the propagation of the signal on the air. It is estimated the accuracy of the definition between the transceivers, based on the time of the signal passing, taking into account the obstacles. In further studies, for the possibility of obtaining alternative results, as well as a more detailed analysis of the measurement error, the laser distance measurement will be included in the sensor network.
