Time resources allocation in cognitive radar system

This paper considers the problem of simultaneously detecting and tracking multiple targets. The main problem discussed here is the time allocation of cognitive radars in a multitarget environment. Radars are used to detect, to locate and to identify target. The radar performs three main functions: search, tracing and weapon engagement. Each of functions occupies amount of time. It is a key point that to allocate radar time ressource effectively. For cognitive radar, it should have the basic function which is learning. The radar needs to manage its resources dynamically and interactively between the setting of radar parameters to optimize the tasks the setting of radar parameters to optimize the tasks to be carried out and perceive environment highlights the role in which knowledge and intelligence will be central in cognitive radar performance. In this paper, we develop the optimization criterion based on the detection probabilities.
