Abstract

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 information on the target and the background, then adapt the transmitted waveform to optimally satisfy the needs of their mission according to a desired goal. Both active and passive radars are considered, highlighting the limits and the path forward. In particular, we here consider cognitive active radars that work in spectrally dense environment and change the transmitted waveform on-the-fly to avoid interference with the primary user of the channel, such as broadcast or communication systems. We also describe cognitive passive radars, that contrary to the active ones cannot directly change the transmitted waveforms on-the-fly but can instead select the best source of opportunity to improve the detection and tracking performance
