The title of thesis is “Radar-Communication Systems Coexistence and Agile Multicarrier Radars”
The ever-increasing demand for radio spectrum requires future wireless systems to share this limited available physical resource. Extensive adaptability of both systems and a new design paradigm are expected. Coexistence among radar and communications systems is proposed in this thesis as a solution to the problem of congested spectrum use. The coexistence methods proposed in this thesis are based on waveform optimization and adaptation and are applicable also to other systems sharing radio spectrum. The need for future radar systems to be fully adaptive and cognitive and take advantage of all available degrees of freedom for optimizing their performance is met by multicarrier waveforms. A generalized multicarrier radar model able to describe most commonly used radar waveforms as well as novel ones in an easy and customizable way is proposed. Using such model novel multicarrier waveforms with improved radar performance are proposed. It is also shown that the radar system can improve its performance by cooperating with the coexisting communications systems.
