Поиск глобального максимума при вычислении оценок местоположения пассивной широкобазовой системой
The algorithm for searching the global maximum of the objective function for increasing the speed of operation of a one-stage algorithm for estimating the location of the radio source of a passive distributed wide-band radar system is developed and investigated. The problem is solved by the transition from the universal gradient method of searching for a global maximum to a search of the values of functions over a sufficiently dense grid in the search domain and further refinement by the methods of searching for a local extremum. The condition for choosing the minimum sufficient step of discretization of space is formulated and three strategies for choosing a step are proposed: homogeneous, heterogeneous and adaptive. Estimates of the gain in run-time and the frequency of occurrence of anomalous errors are given.
