Abstract
A method for optimizing the process of searching for an unknown number of moving targets in conditions of stochastic uncertainty is proposed, which allows to significantly reduce the average time of their finding by a multifunctional radar device equipped with an antenna array. More effective is the optimal managed search, in which the order of viewing different directions is determined in the search process depending on the results of already performed views. One of the important areas of further improvement of radar technology is the transition to antenna arrays with digital beamforming based on adaptive signal processing directly in the elements of the digital antenna array (DAA).
Highlights
One of the important areas of further improvement of radar technology is the transition to antenna arrays with digital beamforming based on adaptive signal processing directly in the elements of the digital antenna array (DAA) [1,2,3]
The main advantage of DAA is the solution of the problem of detecting and tracking a large number of targets in conditions of intense radio counteraction due to the possibility of forming several independently controlled antenna patterns in the reception mode [3]
