The aim is to increasing the efficiency of airspace radar reconnaissance by combining non-coherent signals in a multi-radar system from individual modules. Objectives: analysis of ways for improving the flight characteristics of air objects, analysis of the quality of detection of air objects with low radar cross section, development of a method for processing non-coherent signals in a multi-radar system of surveillance radars. The methods used are: methods of systems analysis, probability theory, mathematical statistics, mathematical apparatus of matrix theory, theory of statistical radio engineering, radar theory. The following results were obtained. A method for processing non-coherent signals in a multi-radar system based on existing radars has been developed. It was found that with non-coherent signal processing, the gain efficiency in the signal-to-noise ratio is 11 dB for a multi-radar system with four radars compared to stand-alone radar. Conclusions: the greatest efficiency for increasing the signal-to-noise ratio was shown by adding second radar. It is established that the optimal number of radars in the multi-radar system is not more than four. Further increase in the number of radars does not provide practical benefits and economic feasibility of creating a system.Read More
