In this paper we consider the resource management task in closely spaced multiposition radar systems. The aim of the work is to develop an investigate approaches of avoiding resource overuse and mutual interference of the radars. We consider two levels of resource management: reallocation of active radars depending on the operational situation in area of responsibility the system to minimize used radar resources, and reallocation of frequency resources between active radars to avoid mutual interference. Fast suboptimal algorithms are proposed for both levels of optimization.
