The Impact of Cognition on Radar Technology — Recommend this title to your library

Cognitive dynamic systems have been inspired by the unique neural computational capability of brain and the viewpoint that cognition (in particular the human one) is a supreme form of computation. Some exemplifications within this new class of systems, which is undoubtedly among the hallmarks of the twenty-first century, are cognitive radar, control, radio, and some other engineering dynamic architectures. Haykin published two pioneering articles in the context of the cognitive radar. The key idea behind this new paradigm is to mimic the human brain as well as that of other mammals with echolocation capabilities (bats, dolphins, whales, etc.). They continuously learn and react to stimulations from the surrounding environment according to four basic processes: perception-action cycle, memory, attention, and intelligence. This last observation highlights the importance of specifying which are the “equivalents” of the aforementioned activities in a cognitive radar.
