Design of a cognitive radar for operation in spectrally dense environments

This paper presents a new idea for cognitive radar operating in spectrally dense environments. In particular, the case is addressed when the instantaneous frequency of the radar, assumed to be a wideband or ultra wideband radar, spans several channels, which are used at the same time by other users for communication services. This work proposes a decentralized frequency sharing protocol, which optimizes the performance of the radar and, at the same time, limits the interference received by the other users.
