An overview of spectrum sensing in cognitive RADAR systems

The spectrum scarcity problem is occurred due to static allocation of the spectrum and increasing no of applications of the wireless communications. The same problem occurs in the field of radar communication. The solution of the said problem is a cognitive radio. The cognitive radio works on the principle of dynamic access. The essential part of the dynamic access is the spectrum sensing. In this paper, an overview of the spectrum sensing techniques in Cognitive RADAR is given that is available in open literature. These techniques will help in the development of self-aware, environment aware RADAR systems which can adapt the target variations in a real time within a short interval of time.
