Unified Cognitive Radar Framework for Multitarget Estimation

Cognitive radar has been popular topic in the industry and research community during the last two decades. It is not a new radar. Instead, it is a radar with cognition, which makes it compatible with legacy radars as well as radars to be built in the future. We are introducing a unified cognitive radar (UCR) framework that includes intelligence, memory, attention, and the perception-action cycle (PAC), which are the elements of cognition, to be incorporated into radar performing multitask in multitarget environment. The UCR based radar can perform several tasks, such as tracking, classification, and discrimination, etc. simultaneously and intelligently by taking advantage of the prior knowledge and the knowledge learned from the environment throughout its operation. This ensures the cognitive radar to maintain its desirable performance in any environment during its lifespan. Simulation results in a simplified scenario are presented.
