The signal processing method based on extremal filtration in low signal-to-noise ratio conditions was proposed. The extremal filtration is similar to the empirical mode decomposition (EMD) method, but complex mathematical calculations are absent that is the main advantage. Using it in real measuring devices significantly increases the speed rate. The extremal filtration process is an algorithm that involves sequentially repeating until an optimal result. The disadvantage of this method is decreasing the spatial resolution since every iteration due to a reduction in the number of samples. It is an especially negative fact in areas of sharp signal change. This paper demonstrates how to solve this problem using linear interpolation and to improve the result obtained by simple extremal filtration.

The article analyzes the development trends of industrial systems called real-time location systems. The systems are based on various basic principles and are designed to solve problems of localization and predicting the position of mobile objects. The characteristics of the scanning information and navigation system are given. It is based on the use of infrared technologies based on PIR sensors [1]. The system consists of distributed scanning cells matrix. Computing cores of cells, implemented on the FPGA platform and represent distributed intelligence. They also perform the tasks of navigation and localization of mobile objects. The modeling of the scanning network fragment in the AnyLogic software package was carried out and the criterion of efficiency was determined. This made it possible to optimize the topology of communication links for the interaction of individual cells when transmitting messages and to determine the limiting characteristics of the network.
