Due to congested wireless radio spectrum, next-generation radar transmitters will need to be adaptive and reconfigurable in real time to share spectrum with wireless communication devices. Typical system optimization methods rely on separate optimization of the circuit and waveform, which can lead to an over-emphasis on one criteria. While the end result may be acceptable, the intermediate results may not be desirable for a real-time situation. In this thesis, a joint circuit and waveform optimization technique is demonstrated that is designed for use in a real-time reconfigurable radar transmitter. Measurement results are presented to show how joint circuit and waveform optimization allows for better intermediate results that allow real-time optimization to be utilized.
