In this report we discuss the mechanisms of cognitive radar. This report is organized as follows: We start with the history of cognitive radar, where origins of the PAC, Fuster?s research on cognition and principals of cognition are provided. Fuster describes five cognitive functions: perception, memory, attention, language, and intelligence. We describe the Perception-Action Cyclec (PAC) as it...

The vision behind software radio (SR) is to realize the communication specific signal processing of a radio as far as possible on programmable hardware. An ideal SR samples the received signal directly at the antenna, and its hardware consists of a general purpose processor that is connected with analog-to-digital and with digital-to-analog converters. A radio that uses an analog radio frontend...

We describe a virtual telemetry system that allows us to devise and augment dynamic data-driven application simulations (DDDAS). Virtual telemetry has the advantage that it is inexpensive to produce from real time simulations and readily transmittable using open source streaming software. Real telemetry is usually expensive to receive (if it is even available long term), tends to be messy, come...

Modeling of complex dynamic systems, which are very complicated to establish mathematical models, requires new and modern methodologies that will exploit the existing expert knowledge, human experience and historical data. Fuzzy cognitive maps are very suitable, simple, and powerful tools for simulation and analysis of these kinds of dynamic systems. However, human experts are subjective and ca...

The field of cognitive dynamic systems (CDSs) is an emerging area research, whereby engineering learns from neuroscience. Under this framework, are configured in a manner that mimics the human brain and improves utility performance traditional systems. In essence, CDS builds on Fuster’s paradigm cognition fulfilled with presence five processes: perception-action cycle, memory, attention, intell...
