Abstract
A method is disclosed for merging detection information produced by various sensors of a detection system formed by a passive radar system including various bistatic bases and by an external sensor. The method includes two processing phases. During the first phase, for each bistatic base of the passive radar bistatic plots produced by that bistatic base are first merged with bistatic plots produced on the basis of plots transmitted by the external sensor and projected into the bistatic base concerned. Then, by associating all the bistatic bases, bistatic tracking is applied to the merged bistatic plots and unmerged bistatic plots coming from the external sensor. During the second phase a cartesian tracking is generated on the basis of bistatic plots that contributed to forming the bistatic tracks.
