Abstract
The detection of space objects at large distances can be carried out by several radar stations, which makes it urgent to develop algorithms for joint processing of radar information received in the presence of interference from several radars. The article discusses procedure for modeling target selection by jointly processing results of measuring its position by geographically separated radar stations. A mathematical model for generating coordinate estimates is shown, taking into account potential accuracy of measurements made by individual radar stations. An analytical expression is developed that allows you to set threshold for selecting true targets that are simultaneously observed by two different radar stations in conditions relayed interference. Based on simulation modeling, obtained graphs of the probability of target selection for various conditions of radar observation of targets by geographically separated radar stations.
Highlights
Обнаружение космических объектов на больших расстояниях может проводиться несколькими радиолокационными станциями, что обуславливает актуальность создания алгоритмов совместной обработки полученной в условиях помех радиолокационной информации от нескольких таких станций
В такой пространственно-некогерентной многопозиционной радиолокационной системе обзора пространства отсутствует фазовая и частотная привязка позиций, при этом основу объединения информации составляет взаимная привязка измерений по времени [3, 5]
