Abstract: In this survey paper we have discussed about the new blooming technology which is Cognitive Radar. It has various advantages over our classical radar as it mimics our human brain and is adaptive to our environment. We have seen the basic structure and the components along with the working of this Cognitive Radar Systems. Keywords: Cognitive Radar, Cognitive System, Principle Components, New Algorithms, Cognitive Radar Networks.
1. INTRODUCTION A growing area, cognitive science focuses on the idea of cognition from a variety of angles, including those of artificial intelligence, psychology, neurology, and many more. It is emerged from the human psychology which has its aim in examining a person’s mental health and different processes.Is the definition of cognition stated by the National Institute of Mental Health (NIMH)National Institute of Health (NIH) [1-2]. In other words, cognition can be said to be the ability of a conscious mind that is aware of the environment. It includes tasks like thinking, reasoning, judging and problem solving [3-5]. Isn’t this what makes humans intelligent than all other species. We do not understand its importance as we are unknowingly using it in every aspect of our day-to-day life [6-10]. So, this incorporated in Machines too for making our tasks easier [11-13]. New innovative ideas are implemented in engineering systems for making this successful. This is present in our industry since many years and has proven beneficial in fields of signal processing [14-16], telecommunication, control, radar systems and domestic applications like traffic control too [17-19]. This increases the performances of the systems by decreasing the time taken and helps us focus on the systems where human interactions are needed [2021].Though the idea of cognitive systems is not yet developed, there are a lot of unanswered questions that includeproblems likepractical implementations in engineering and how beneficial they can be to us [21-23]. For the last fifteen years, cognitive principle has gotten a lot of attention and has become more significant in disciplines including signal processing, communications, and control. Some of the presumed factors are that the application of this radars can motivate us to build new integrative discipline, focused radar, control systems interlinked to humans and cognitive dynamic system [24-27]. It is cognitive when a dynamic system can perform all of the human cognition characteristics, such as acting based on the information we get, storing memory, paying attention to all the details and being smart [28-29]. Because of the cognitive function, cognitive dynamic systems often detect the environment intelligently and responds to it adaptively [30-34].
