Алгоритм обработки акустических сигналов при обнаружении беспилотных летательных аппаратов - Рыбников, Н. В. (My University, 2020)
The work is devoted to the development of a new method for processing broadband acoustic signals of an unmanned aerial vehicle, which allows to increase the efficiency of detection algorithms. The problem of optimizing the spatio-temporal processing of the received acoustic signal by the criterion of the maximum ratio of the useful signal / interference at the output of the antenna array is considered. The necessary mathematical relations are obtained that determine the processing sequence of the received acoustic signal. The vector of optimal weighting coefficients is formed in accordance with one of the known criteria for the optimality of spatiotemporal processing, for example, in accordance with the criterion of the maximum signal / noise ratio.
