Future radar transmitters must be adaptive and reconfigurable in real time to be able to share spectrum dynamically with wireless communications. We demonstrate the joint, back-and-forth optimization of the radar transmitter waveform and circuitry in a combined algorithm that can be used for real-time reconfiguration. While previously developed methods consider the waveform and circuit separately, resulting in emphasis on one of the criteria [ambiguity function (AF) or power efficiency], we show that the joint optimization of the circuit and waveform allows both the radar AF and circuit power-added efficiency (PAE) criteria to be gradually improved during the optimization. Measurement results are presented and analyzed to assess the convergence of the PAE and AF least-squares error, as compared to the AF template during an optimization under spectral mask and peak-to-average power ratio constraints.
