Cognitive radar is a radar system that acquires knowledge and understanding of its operating environment through online estimation, reasoning and learning or from databases comprising context information. Cognitive radar then exploits this acquired knowledge and understanding to enhance information extraction, data processing and radar management. In order to make progress to this goal, the topic of cognitive radar attempts to shift the cognitive processes previously performed by an operator into automated processes in the radar system. Families of cognitive processes are well defined in cognitive psychology [1], such as the perceptual processes, memory processes, languages processes and thinking processes. In this chapter, we discuss radar management techniques that enable the manifestation of one or more cognitive processes, with a particular view towards electronically steered phased array and multifunction radar systems. In particular, this chapter focuses on two cognitive processes: attention and anticipation. Attention can be manifested by effective resources management, whereby a quality of service-based task management layer connects radar control parameters to mission objectives. Anticipation can be generated using stochastic control that is non-myopic, allowing the radar system to act with a consideration of how the radar system, scenario and environment will evolve in the future.
