由于频谱准则的收紧，雷达发射机的波形和电路的联合优化被认为是最小化的非线性和波形引起的频谱扩展的雷达发射机。本工作演示了在两个线性调频脉冲激励下，功率放大器的ACPR负载牵引测量。结果进行比较，以允许选择最佳的啁啾和发射机负载阻抗。这项工作代表了一个开始的努力，实时，计算智能发射机优化在未来可重构雷达系统。
Due to tightening spectral criteria, joint optimization of radar transmitter waveform and circuit is considered to minimize the nonlinearity and waveform induced spectral spreading of radar transmitters. This work demonstrates the ACPR load-pull measurement of a power amplifier under excitation from two chirp waveforms. The results are compared to allow selection of the optimum chirp and transmitter load impedance. This work represents a beginning effort toward the real-time, computationally intelligent transmitter optimization in future reconfigurable radar systems.
