A radar architecture for joint dynamic spectrum access and target-matched illumination

In this study, we address a simple cognitive architecture to design a radar waveform that fills the gaps in the radio-frequency spectrum and matches the target scattering properties. The metric used to calculate the radar waveform is the Mutual Information between the received signal and the target impulse response. Particular attention is paid to analyse the impact of the properties of the communication signals on the chosen metric, for both ideal and non-ideal cases.
