Cognitive radar: Waveform design for target detection

Cognitive radar is an emergent technique in modern radar system development. Cognitive radar achieves new levels of radar performance by leveraging mechanisms present in biological systems and incorporating them into the function and operation of the radar system. Here recent developments and future directions of cognitive radar are presented with a focus on the detection of radar targets. These studies require a deeper examination into both the nature of the operating environment and the characteristics of targets themselves. Additionally, sources of interference which serve to impact radar performance are examined under the framework of cognitive radar and promising interference mitigation techniques are reviewed.
