未来的雷达系统必须适应动态频率的限制，同时最大限度地提高目标探测范围。然而，提供最佳功率的阻抗终端随频率和阵列扫描角而显著变化。为了在工作频率和扫描角度变化时保持良好的检测范围，我们在发射机功率放大器和发射天线之间引入了高功率可重构电路。这种可调匹配网络及其快速调谐算法将在软件定义无线电（SDR）平台的控制下实现，以实现实时优化。
Future radar systems will must adapt to dynamic frequency constraints while maximizing target detection range. However, the impedance termination providing optimum power changes significantly with frequency and array scan angle. To maintain good detection range over operating frequency and scan angle changes, we introduce the use of high-power reconfigurable circuitry between the transmitter power amplifier and transmit antenna. This tunable matching network and its fast tuning algorithms will be implemented under the control of a software-defined radio (SDR) platform to allow real-time optimization.
