This article describes some key ideas and applications of cognitive radars, highlighting the
limits and the path forward. Cognitive radars are systems based on the perception-action …

This study deals with the problem of spectrum sensing and spectrum sharing for cognitive
radar operating in spectrally dense environments. The authors focus on how compressed …

Radar technology has been evolving towards higher resolution, high-precision detection
instruments with an ever-increasing list of functionalities. One of the areas, which have very …

Regulatory bodies have predicted an impending shortage in commercial radio frequency
spectrum in the near future. However, due to outdated regulatory practices, many of these …

The interdependency, in a cognitive radio (CR) network, of spectrum sensing, occupancy
modelling, channel switching and secondary user (SU) performance, is investigated …

This paper focuses on some applications of cognitive radars. Cognitive radars are systems
based on a perceptionaction cycle that sense the environment and learn from it important …

Compressed Sensing is a new signal processing methodology that allows to reconstruct
sparse signals using a relatively small number of samples in the form of random projections …

Combining spectrum sensing (SS) and primary user (PU) traffic forecasting provides a
cognitive radio network with a platform from which informed and proactive operational …

This paper deals with the problem of a cognitive radar system that shares the same
frequency band with a communication system, supposed to be the primary user of channel …

A Cognitive Radar, working in a frequency dense environment, has to perform effective
wideband operations, spanning several frequency channels, by working in parallel with …
